Woolwax® FAQ

Woolwax® FAQ


What is the difference between Woolwax® and other lanolin film type products ?

Woolwax®  is made from lanolin/woolgease. It contains more woolgrease and is more resistant to wash-off than any competitive product. In short...Woolwax® lasts much longer, has almost no smell, very little over-spray because it is thicker, and is available in clear and Black.

* Woolwax® is  made from woolgrease (lanolin) which is an excellent corrosion inhibitor & Lubricant.

* Woolwax® is solvent free, safe, non-hazardous, environmentally friendly.

* Woolwax® has a proprietary process to remove the woolgrease smell which can be very strong and some people do not care for it.

* Woolwax® is formulated to be more viscous (thicker) than any other lanolin based corrosion inhibitor, thereby being more resistant to road-wash. Woolwax® may need to be warmed up in front of a floor heater in cold weather before applying.

* Both products can be easily sprayed with the "PRO" Undercoating Gun from Kellsport Products. Woolwax® being thicker, has much less overspray (misting).


Woolwax® is geared more towards the industrial user, professional undercoaters, or users in areas with heavy amounts of road slush that may want a slightly thicker product for more resistance to wash-off with very little noticeable smell.


What is Woolwax®

Woolwax® is a lanolin (wool-wax) based, solvent free corrosion preventive designed for use on any known metal. Woolwax® has a thixotropic viscosity that allows for a thick and drip free coating. Woolwax® leaves a soft, grease-like self-healing film that can be applied by brush or spray applicator gun. Woolwax® will not dry out and will penetrate metals to the base, providing corrosion protection in highly corrosive atmospheres like those found in industrial or environmental settings. Woolwax® has proven to be an exceptional vehicle undercoating product.

Applied annually to the vehicle undercarriage, frame, doors, etc., Woolwax® will provide excellent rust protection for any vehicle. Because Woolwax® is solvent free, there is no evaporation process.  Woolwax® coating in protected areas such as doors, frame rails, rocker panels, etc. will provide protection indefinitely (years).  The exposed area of the vehicle undercarriage is an annual maintenance application.  A Woolwax® treatment in the fall is generally adequate to get the vehicle undercarriage through the winter/salt season. Woolwax® is not a rust remover or converter, however Woolwax® can be applied over existing surface rust. Woolwax® will form a heavy film and prevent moisture and oxygen from reaching the existing rust. Thereby stopping it on contact. Heavy bubbling or flaking rust should be wire brushed before applying Woolwax®.


Woolwax® seems very thick. How is it applied ?

Woolwax® is very thick. We formulate it to be as thick as possible, yet easily sprayed.  Woolwax® is a heavy duty industrial grade lanolin vehicle undercoating that will survive the harshest weather and provide rust protection longer than any other annual undercoating. Woolwax® is thixotropic, and will thicken as it sits. Before applying shake or stir Woolwax®  vigorously. In cold weather it helps to warm up the Woolwax®. This can be easily done by placing the container in a warm area , or placing the spray gun bottles in warm water. Woolwax® is best applied using a Woolwax® undercoating gun. These guns are modified specifically for the waxy texture of the lanolin/woolwax.

Woolwax® can also be painted on surfaces depending on the application.


Does Woolwax® have a strong odor ?

No. Unlike other vehicle undercoatings Woolwax® has almost no smell at all. Through a proprietary process we have neutralized almost all of the strong lanolin/woolgrease odor. Also, because there are no solvents, there is no "chemically" smell to Woolwax®.


What type of compressor is needed to apply Woolwax®? How much psi? 

Woolwax® undercoating guns do not require much pressure. 70 – 90 psi is usually adequate. Sometimes the extension wands require a bit more pressure if it is cold out. Even small compressors generally operate at about 125 psi. More important is the tank size. If the tank is very small, you will be constantly waiting for the compressor to recover. Generally speaking, any compressor with a tank 3 gallons and larger will work fine. If the compressor is adequate for spray painting, it will work fine for vehicle undercoating.


Can Woolwax® be applied with an airless spray system?

Yes. We do not recommend airless systems for do-it-yourselfers because of the dangers of the very high pressure (2000-3000 psi). That being said, many of our high volume undercoaters do use airless sprayers and the feedback is that they work extremely well with airless spray systems. The recommended tip size for Woolwax® is tip # 213. 


What color is  Woolwax®

Woolwax®  is available in a straw color, which appears fairly clear when applied. Woolwax® is also available in black.


Where is Woolwax® made?

Woolwax® is manufactured 100% in the U.S.A. The only raw material imported is the woolgrease, because it is not available here. Everything other raw material, and the packaging, labels, boxes, tint(black), is proudly manufactured in the U.S.A.


Where can I get my vehicle treated with Woolwax®?

We have hundreds of undercoaters throughout the country that apply Woolwax® to customers vehicles. Enter your zip code on our website under “Find an Undercoater”. If there is no location near you, consider purchasing one of our Do-It-Yourself kits. All you need is a small compressor. Woolwax® is non-toxic, non-hazardous, and very easy to apply.


Is the Woolwax® spray aerosol the same as the bulk product (Gallons, etc.)?

Yes. However, since the can is under extreme pressure, the Woolwax® will spray in a lighter mist coating. The spray cans are great for general maintenance applications and touch-ups. The aerosols will not provide the same heavy thick coating that the bulk product (gallons, pails, etc.) will. If you are not in a snowbelt state with a lot of long-term road slush, undercoating your vehicle with spray cans will work well. Otherwise we recommend applying a heavier coating from the bulk container (gallon or pail).


What is the shelf life of Woolwax®

The shelf life of Woolwax® is indefinite. There are no solvents, so nothing to harden or evaporate. The aerosol spray cans are guaranteed for (1) year because the propellant can weaken after time.


Can Woolwax® be applied with a pump (garden type) sprayer?

No. Woolwax® is too thick to flow through any type of garden sprayer. (We have tried most of them.)


How can I thin Woolwax® if it is not flowing through my gun good enough?

Woolwax® is thixotropic and will get thicker as it sits. The first step is to mix it up extremely well. Warm up Woolwax® by placing it in front of a heater or placing in warm water. If it still needs to be thinned, you can mix in a small amount of vegetable oil until it is at the desired consistency. 


Can Woolwax® be applied over existing rust?

Woolwax® can be applied over any existing surface rust.  Woolwax® will stop the rust from progressing on contact by creating a film barrier that wil prevent moisture and oxygen from getting to the base metal. Woolwax® is not a rust converter or remover. Any heavy bubbling or flaking rust should be brushed off before applying Woolwax®.


If Woolwax® stays wet, will grass and stuff stick to it?

Because Woolwax® is non-drying, Woolwax® works as a release agent. Grass and other debris do not stick. Anything that may adhere can easily be rinsed off with a low pressure garden hose.

Woolwax® is very thick and does not wash off easily.


How do I clean the undercoat gun after use ?

Our Undercoat guns do not need to be cleaned after use when using with Woolwax®. Woolwax® undercoating is solvent free, so there is no evaporation or hardening process. The Woolwax® left in the bottle will thicken over time. But you can restore to its original viscosity by shaking vigorously.

Some people do prefer to clean the gun and wands. To do this we recommend just putting some solvent (acetone, mineral spirits, paint thinner, etc.) into one of the bottles and spraying a bit through the gun.  Some people just put water and dish washing liquid into the bottle, and they say that it works fine.

Most people just leave the gun loaded and ready to go without doing anything at all.  That way you can do a quick touch-up or spray some outdoor power equipment with almost no setup time.

Bottom line……. Don’t worry about the undercoat guns when using Woolwax®. They won’t clog.

How often does my vehicle need to be undercoated ?

Woolwax® is an annual maintenance application.  A Woolwax®  treatment will easily provide protection through even the harshest of winter conditions. Woolwax® is extremely resistant to wash-off. Woolwax® contains no solvents, so there is no evaporation process. In the protected enclosed areas (doors, frame rails, etc.) a single treatment will provide protection for an indefinite period of time (years). The exposed area of the undercarriage should be re-treated annually. There is no need to remove or power wash the existing Woolwax®. Simply give it a rinse with a garden hose to clean it up a bit, and apply a fresh coat right over the existing Woolwax®.  Many of our Undercoaters suggest treating vehicles in the warmer weather so that the Woolwax® creeps and migrates into all the inaccessible areas.  

If Woolwax® stays wet, won't it wash off ? 

Woolwax® is extremely resistant to wash-off because it is so thick. In the enclosed protected areas Woolwax® will last for years. The exposed areas of the undercarriage needs to be reapplied annually. 
Woolwax® forms a lanolin film barrier on the base metal that moisture and oxygen cannot penetrate. Without these (2) components, corrosion cannot occur. Because Woolwax® does not dry, it is self-healing. If something scrapes it or road debris hits it, the Woolwax® will "gel over" and repair itself.

My  Woolwax® PRO Gun does not seem to spray well. What can I try ?

  • Make sure the Woolwax® has been stirred or mixed very well.
  • If you are having an issue, fill one of the quart bottles with water and try. If it works with water, we know the gun is operating fine.
  • The Woolwax® may need to be warmed in cold weather. Store it inside. Place container in front of a floor heater for 5-10 minutes if necessary.
  • When the brass nozzle is screwed all the way in, it is in the "closed position". Nothing will come out. Back the nozzle out at least 1/2 way.
  • Increase the Pressure up to 110-120 psi if necessary. Normal operation is 70-90 psi.
  • Flexible extension wands- In colder weather to warm the Woolwax®, and increase the pressure (110-120psi) to push the Woolwax® through the wands. Do not screw the extension wands in very far on the gun. Screw them in just a turn or two so that the connection is made. Hold the trigger down for a few seconds to give the Woolwax® a chance to flow. The extension wands are generally used in areas that are protected from the elements (doors, frame-rails, etc.). If necessary you can thin the Woolwax® with some vegetable oil to get it to flow through the wands in colder weather.
  • Keep in mind that the very cold air coming from the compressor will cause the Woolwax® to thicken. You may need to switch bottles as they get cold.
  • If you cannot resolve any issues, please just give our techs a call at 888-341-4600. We will take good care of you.


 Why are the USD prices different on the Canada site from the USA site?

It is very frustrating to us that we have to charge more on the Canada site.  We have tried every solution possible to keep the costs down, however shipping cross border is just very expensive.

a) Shipping costs within the USA are very competitive.  When shipping USA to Canada, there are only (2) players. UPS and Fedex. Our shipping costs are 34%+/- higher shipping to Canada verses the same mileage based rates in the USA.

b) Every shipment into Canada must clear Canada Customs. Even though there is no duty because of NAFTA, the shipment must clear, and UPS provides the broker service. On our Pro Gun which is $89.50, UPS charges us $19.95 for customs clearance plus a $5 entry fee.  And that is in addition to the regular shipping costs.

c) Taxes- All the GST and Provincial taxes are included in the price. In some cases that amounts to 15%. In addition we have to contract with another company to collect and remit all these taxes to the federal government, as well as each province.

d) Our credit card processing fees are normally about 3%. For international sales they are almost double, due to the increased risk and the currency conversion.

Hopefully at some point things will make it possible to sell Woolwax® at prices similar to the costs in the USA.
