ZERO RUST APPLICATION TIPS

Thin 20% for spraying. (5 parts Zero Rust to 1 part thinner)
The color black is slightly thicker and should be thinned 25% (4parts Zero Rust to 1 part thinner.
Despite what the can label says it has to be thinned to spray!

Set gun pressure to manufacturer's recommendations.

It can be thinned with lacquer thinner or a urethane reducer like PPG's DT-870.
Use a medium temp.; not a slow dry! Acetone is also an acceptable thinner.

Apply in medium coats allowing each coat to dry to the touch. (I like to allow a full 20-30 minutes between coats). This is the most important thing to remember with Zero Rust!
NEVER spray heavy wet coats. Because it seals so well, you'll trap solvents and be left with a soft finish for a LONG time. Don't rush it...be patient!

I suggest 3 medium coats for proper coverage & protection.

The full cure can take from only a couple days to a couple weeks depending how wet the coats are applied. It will get tougher and harder with time.

Zero Rust accepts recoating easily and only needs a light scuff if after a week. Deep scratch sanding is not necessary or desired. When recoating with urethanes, apply a light first coat to prevent shocking the finish. Allow this first coat to dry to the touch and then proceed with a normal coat. This procedure will help prevent a lift problem. I recommend waiting to recoat Zero Rust until it is dried firm before recoating. It is most sensitive to lifting the day after applying and up to one week.


Zero Rust can be used in hidden areas such as inside doors, deck lids, etc. by thinning it 40 to 50% and pouring it into the cavities. When thinned this way it will penetrate through the seams. Follow with a coat mixed 20% to build the film thickness. Itís usually best to coat inner areas first. Coat the inner surfaces by rotating the part. Excess can be drained back into a container for future use. Be sure to "mop" up any overflow drips.
