There was a guy who posted on another web board that he sprayed some Omni 2.1 VOC clear over some rattle can enamel. He applied 6 coats of enamel and baked it prior to spraying the clear. He reported that it turned out perfect.

When planning to apply any automotive clear coat, it would be a REAL good idea to mix some hardener into the rustoleum. Hardener will increase the chemical resistance of the paint significantly. Of course the hardener contains the isocyanates which means it must be done in a safe location and with the proper safety gear and equipment. Hardener smells real bad!! Neighbors, the little woman, and even your dog will be mad if subjected to the smell of it!

One exposure to isocyanates can injure a person for life. These chemicals can cause all kinds of health problems. Asthma is one of the more common problems caused by isocyanate exposure. But there have been some deaths attributed to these chemicals as well.

To achieve adequate personal protection the correct gloves, painters suit, respiratory and eye protection is a minimum. Don't assume just any respirator will do the job. Read the fine print and make SURE it's rated for isocyanates, not just paint. Many "painting respirators" are NOT rated for isocyantes. The eye protection must protect against paint splashes, fumes and overspray.

Sufficient ventilation is essentail when dealing with isocyantes. The worse the ventilation, the higher the potential concentration of isocyanates. Some respirators will only last 15 minutes in an environment with a high concentration of spray mist. The same respirator may last 6+ hous in a low concentration environment. The problem is that isocyanates have no smell so it's impossible to know when the respirator has ceased to filter them out of the air. A supplied air respirator is safer.

To achieve sufficient ventilation a BIG fan(s) is required. Paint booths in automotive body shops often have fans driven by 5 hp electric motors. A home painter may or may not need that large of a fan. It will depend on the size of the booth, etc.

The previous paragraphs are only an outline of the necessary safety precautions. (This off the topic of rolling paint on one's car at home) So do some additional research on how to safely apply paint with isocyanates. There is a LOT of info on the internet, in books, from paint manufacturers, etc.

Just remember, there is not a car on this planet that's worth destroying a person's health over, so be safe!!
