WoolWax® Undercoating Formula is a lanolin based corrosion inhibitor developed solely to protect the undercarriages of automobiles and trucks.

 

Lanolin is blended with other proprietary agents to provide long term corrosion protection. WoolWax provides long term protection, with annual applications, against salt, liquid calcium chloride, brine, and all other ice control agents that are being used by todays municipal departments.

Most other undercoating products contain up to 70% solvents, which make these products very thin and watery. Without a very thick viscosity, these products break down and wash off quickly.

 

WoolWax is solvent-free and very thick and viscous. It applies like a heavy latex paint, which makes it very resistant to wash-off. WoolWax does not dry. It remains soft and pliable and continues to be active—migrating into inaccessible areas.

Why are you spraying over rust?

You are wasting your time—you can't paint over rust! You are  just covering up the rust.

 

WoolWax is not just "covering it up". WoolWax is a corrosion inhibiting protective coating that will seal out any moisture and oxygen from from getting to the base metal, or existing rust.

 

Three things must be present for rusting to occur: iron, oxygen and water. Rust forms when these three elements combine and create an electrochemical reaction. Iron plus water plus oxygen equals hydrated iron oxide (Iron + water + oxygen → hydrated iron oxide). It is the hydrated part that makes rust brown instead of red. If any one of these components is missing, the rust cannot progress. Rust can’t form without water. Rust can only form in the presence of oxygen.

 

WoolWax will stop the existing rust from progressing on contact by creating a film barrier that will prevent moisture and oxygen from getting to the base metal. This protective coating will provide protection for at least two years before requiring a touch-up.

Salt accelerates the rusting process by corroding the metal. This is a factual science. Anyone that tries to say that rust will still progress under a good protective coating is simply mistaken. Perhaps they have tried to cover rust with paint that was not designed as an anti-corrosion coating. Perhaps they are just repeating what they see from internet "experts". Actual users that have tried WoolWax (and other good quality protective coatings) know that they are extremely effective in stopping rust.

Would it be better to remove all the rust and bring it down to bare metal? Of course! But in most cases the expense required to sandblast, needle scale, wire brush, prime and coat the undercarriage would be cost prohibitive. And even then, you would not be able to remove all the existing rust in the inaccessible interior protected areas (frame rails, rockers, etc.)

How Do You Stop Existing Rust and Prevent More Rust?

 

Preventing rust is a never-ending battle.

 

The way to stop more rust is to cut off one of its sources, like oxygen and water. Do this by applying a thorough coating of WoolWax. 

 

Because there are so many ways that metal can become exposed to oxygen and moisture the key is to make sure the metal is completely covered. Doing so ensures that oxygen and moisture can’t reach it.

 

You will be very pleased with the results over the long term, especially if you make this a part of your maintenance routine.
