I recently bought some alcohol-based paint. I have as yet never used such a paint so I have no idea if I need to do anything differently than I normally do with Enamel or Acrylic paint.

Are there any reactions to other paints or varnishes I should avoid?

Which paint is that?

Anyhow there aren't any alcohol-based paints, however there are paints and lacquers that use alcohol solvents
in the carrier. Shellac is the classic being flakes of lac - product of the bug of the same name, dissolved in alcohol.
Tamiya and GSI-Creos water reducible paints are an acrylic resin base dissolved in a carrier of alcohols and glycol
esters, which is why they can be thinned with both alcohols and lacquer thinners. The lacquers from Tamiya and
GSI-Creos are basically the same acrylic resin in a hotter hydrocarbon carrier.

Nor are water-based paints actually water based, they have a synthetic resin base of some sort - acrylic, acrylic latex,
polyurethane, latex, butyrate etc., suspended in a carrier that is primarily water.

Oil-based paints aren't called oil-based because they use hydrocarbon solvents, it's because the resin base that forms
the paint film is derived from oils from various sources, primarily from plants, although fish-oil has also been used.

The main thing to bear in mind is that any paint that can be removed/dissolved by alcohol after it has dried/cured will
be effected by a paint containing alcohol solvents. Which can be a non or minor issue when airbrushing, but definitely
problematic when using a brush. Basically I'd say next to/over cured enamel or lacquer no issue, under lacquer OK,
under enamel probably - if the "alcohol" paint is cured, but if using Vallejo, or similar, over the "alcohol" paint but not
under.

This





As the enamel paint surface that I am going to paint on top of has been sat for well over a week I should be ok then going by what you wrote @jcf .

Not enough of it!

I would strongly recommend preparing a test piece before putting that over enamel on something you care about.
A plastic spoon is traditional.
Don't ask me why I suggest this...
