The paint on the moldings around the rear quarter panels on my 1927 coupe is in fairly good condition. They are removed. I am thinking of sanding it, priming it with Rust-Oleum, and top coating with Rust-Oleum Gloss Enamel.

I am pretty sure that it is the original paint. My question is "Any concerns about the Rust-Oleum reacting with the existing paint?" Also, do I need to use a prime coat?

Bruce, you could trial your precedure on the inside of the moulding and see what happens.

As Allen suggests, you could try the compatability somewhere inconspicuous That's the only way to know for sure.

The one thing I would suggest is to omit your primer step. If the existing paint is sound, then it's probably the best primer you could ever have. The only caution is that you should clean and break the glaze to ensure the new coat will adhere.

An advantage to the black-on-black coats is that any future chips or scratches don't show as much.

Would a trial on an inconspicuous location show a incompatibility problem immediately or could this be a problem that would show up much later?

Bruce, it depends. Sometimes the process does take some time for the new topcoat to blister/craze whatever. You may be able to accelerate the reaction by mixing more of the new paint thinners into the paint you want to use. For what it's worth, I use a spray can of epoxy enamel for such applications. Enamels will cover all sorts of substrate with few ill effcts. The only Rustoleum I have used was lees than satifactory for me.
