It was shot in Alkyd and it was one of my better jobs, sans thumb print. Seems like the Alkyd paint is slower to dry because of no added hardeners. Was thinking of taking some 1000 paper to it and wet sanding it and see. Go from there.

put it in the sun for a week at least before any attempts to sand.
Give me ambiguity

The solvent evaporates out pretty quickly, but the carrier of the pigment ("binder") needs time to oxidize and harden. When quick-curing acrylic enamels and isocyanate hardeners came on the market about 40-something years ago, people started to forget how much hassle alkyd was to deal with. About the only place I see alkyd enamel for sale any more is "tractor and implement" paint, sold by farm equipment places like Co-Op, or Tractor Supply Co., etc.
The cyanide-based chemicals in isocyanate hardeners are contact poisons, meaning they can be absorbed through the skin. To use them safely, it's necessary to wear a full-coverage "shoot suit", preferably one with a separate air supply drawn through a good chemical filter. Some of my painter friends who used isocyanates on a regular basis have developed some pretty nasty chronic health problems from the toxicity of the products.

Assuming it is fairly fresh, carefully press a smooth shiny object onto the thumb print, like the back of a spoon. Just enough to flatten out the margins. Orient the bumper so that the mark is level and horizontal. Mix a little bit of the paint with a slightly higher than recommended ratio of Naptha. Use a small paint brush to fill the mark, making sure the paint is slightly higher than the surface.
Leave it for a couple of days indoors.
The solvent will soften the under lying paint and the edges will blend.
You will have the a slight blemish at most and no one will notice it.
Hint, always use hardener. The paint is much stronger and you can handle it after 24 hrs without leaving marks. | | |
