Looking for a permanent 1-time hard shell coating for your truck frame or equipment?  Hard-On by woolwax™ is what you need. Originally developed as a chip guard for trailer trucks this formula is perfect for any long term applications.  Hard-On is water based , so it has almost no smell. Dries to the touch in about 1 hour, and after 72 hours it is fully cured. 

Hard-On by woolwax™  was developed to be used on both ferrous (steel, stainless steel, cast iron, and wrought iron) and non-ferrous metals (aluminum, brass, copper, tin,).  In addition, this formula will adhere to primers and oily steel.  Hard-On can be recoated with most urethane, acrylic or resin formulated automotive topcoats. 

Hard-On by Woolwax™ is an excellent solution for wheel wells which is always a high wash area. 

Hard-On™ is a water based coating that can be used on any metal surface.  No smell. Paint or spray on. 

Woolwax Hard-On is a high performance, permanent 1-time hard shell coating. NOT rubber. For those people that want a "1 time"  application, as opposed to an annual maintenance products, Hard-On is a great choice.  If you decide to go with Hard-On permanent coating, you will also need a cavity wax for the enclosed protected areas. We highly recommend Creep N' Crawl Cavity wax. This can be found at the the link here:  Creep N' Crawl Cavity Wax. 

Hard-On can easily be sprayed or painted on the surface.

** Hard-On by woolwax™ is not high-heat resistant. Typically undercoating formulas primary function is as a corrosion inhibiting agent. Developing a coating that is also high-heat resistant is not an option due to the cost being to high to sell to the majority of undercoating users. It is very costly to make it high-heat resistant.

     Hard-On by woolwax™ will burn off at 140° F and should not be applied to tailpipes, mufflers, engine blocks, etc. A typical heat resistant coating will tolerate 800 - 1000°F.

     If you are not sure that you want a permanent (cannot be removed) coating, please contact us for more information.  Once applied, there are no do-overs.  Please consider this carefully. 

     Spray Guns-  Hard-On by woolwax™ is a relatively low viscosity water-based coating and can be applied with almost any undercoating gun.
