Sorry, Kreth.  I've never used Acrylic Enamel on any of my planes. 

I have used acrylic enamel for years, and it is entirely fuelproof.  Arlan my son shot some black acrylic enamel on a fuselage and wanted to do silver trim for the canopy.

I have some acrylic polyurethane in silver and was not sure about compatability.

I know somethings about paint.There are two kinds. Mechanical bond and chemical bond. Your chemical bond paint are your lacquer's and dopes. You mechanical bonds are enamel and urethanes. You can put any mechanical bond paint over chemical bond but never put chemical bond over mechanical.

The chemical bond paint are usually thinned with a MEK or lacquer thinner while the mechanical bond paint are thinned with Naphtha based thinners or mineral spirits.

The answer is right in the response I stated. It should work. However I would try a test piece. Both of those paints are mechanical bond paints. Scuff it up first with gray scotch bright (600) as stated it is mechanical bond. It needs tooth to stick. I do something that is not suppose to be done ,like putting Urethane (mechanical bond) over dope (chemical bond) I do it all the time with no ill effects. I don't think it would matter to do it the other way around either. Meaning catalyzed paint under dope. Except it would be difficult to make it stick. I hope this has now answered you question.

Dopes and Lacquers are chem bond

enamels and urethanes are mechanical. So what I am saying is if the paints are of like types the should work together.

In the old days of Aero Gloss you can paint Sig or Randolf over it but never Aero over anything as it has MEK in it.
