RE: What paint to use
It's unfortunate the health hazards that one has to deal with when using Automotive products. They are great!
Certainly there's no better a paint than the offerings in this industry.
The "dopes" would be my second choice, only because I'm familiar with them.
There are "industrial" grade enamels that would certainly achieve a better result than any water base product.
Yes, they are now painting cars with water base paint. However,this painthas to be cleared with a two part product. Back to the hazard.
This model was painted with automotive paint. The lettering, actually Gold Leaf, was applied with a brush. The chemical is called Gold Leaf Size. The black shadow and outline on the gold leaf lettering, was done with One Shot lettering enamel, applied by brush..
Some of the other painted detailing, the pink and blue,was done with a lacquer base paint product, which is no longer available, and applied by brush.
The entire model was cleared with Dupont clear, two generous coats.
