## Description

WOOLWAX is a lanolin based auto / truck undercoating made from raw woolgrease. WOOLWAX has almost no smell. The wool grease odor has been neutralized by a proprietary additive. WOOLWAX sprays on wet and does not dry. WOOLWAX creates a wet thin lanolin film barrier to keep moisture and oxygen away from the base metal. * Solvent free. Environmentally friendly. * Always active and creeping into inaccessible areas. WOOLWAX will thicken to a film after applied and is very resistant to wash off. * Provides vehicle undercarriage protection for a full season. * Enclosed areas (doors, frame-rails, rocker-panels, etc., that are not exposed to road-wash will be protected indefinitely (years). This is the advantage of no solvents. There is nothing to dry up and evaporate. WOOLWAX is a non-drip formula. We make it to be as thick as possible to resist wash-off, yet still easily sprayable. WOOLWAX can be applied with most undercoating guns using a pressure of 70-90 psi. Proudly manufactured in U.S.A. WOOLWAX lanolin undercoating is formulated to be more resistant to wash-off. Woolwax does not dry. It goes on wet and stays wet so that it is self-healing and always active. Will provide protection for up to 2 years. The enclosed protected areas (doors, framerails, rockers, etc.) are protected indefinitely. Woolwax will creep and migrate into all the pincj welds and seams of the metal. There is no need to use a thinner product that leave very little surface build and will not protect as well. On enclosed areas surface build is everything. Thin formulas will creep and the surface build gets thinner and thinner all along the way until the coating is so thin, there is almost no surface build to provide protection. Bottom line.... original thick Woolwax (or any viscous coating) will provide better protection for enclosed areas (frame rails, etc.) than thin formulas that leave a very thin surface build.

Review: Rustproofing at it's best! - If you want a permanent solution for stopping rust this is what you need! This stuff goes on without strong odor and washes off your hands easily, but stains your clothes so wear something you don't care about. The clear is hard to see and if you are spraying it over rust you'll still see the rust, the black works better for that. As with anything the better you do the job the longer it will work. It will creep into pinch welds and other places that moisture gets and seals it up. I would never ever get any type of undercoating that hardens up to stop rust or seal against rust. The type like the rustproofing places uses goes on over anything that is on the metal and will seal in the moisture and dirt and when it gets hard it peels off and the rust is way worse than before it was coated in the first place. I will tell you that if you think that 3 quarts of black and 1 quart of clear will do the job, order extra and save yourself the waiting time for the next gallon to come. I used 2 gallons of black and 2 quarts of clear to do my 2000 F150 and I just got one more gallon to do the areas that I didn't have enough to do, I'll be taking out my taillights and spraying everything in that area, and my front fenders where the front door hinges are. So just order about double what they tell you and have enough to do a re-coat later if you don't use it all. I hope this helps!

### ⭐⭐⭐⭐⭐ Coats Nicely
*by J***D on December 25, 2022*

Employing Woolwax undercoating, with Woolwax's gun and an air compressor, I was able to do my F250 by myself. Once you figure out the nozzle, the undercoating goes on consistently without any harsh chemical smells, drips, or splash back. I was worried that I need a ground cover, but the undercoating stays where it is sprayed. Don't read too much into the pictures, I recognize that I missed spots. Getting a little long in the tooth to be crawling under vehicles, but I think I got the spots that mattered. I'll add that 1 Gallon was sufficient for a light coat on my truck. I didn't coat every inch, but I hit the frame pretty well, and body seams. I've got a solid quart left.
