Here is my most recent finishing sequence. I am happy to report that all the products worked well together, and particularly that the clear didn't affect the lacquer, decals, or ink lines.
Base: 3/4 oz glass cloth and finishing epoxy over wood, Super-Fil fillets
Primer: NAPA DC540 aerosol gray primer
Color: Duplicolor Perfect Match aerosol acrylic lacquer
Trim: airbrushed dope for canopy, water slide decals from Bill Calkins, IdentiPen permanent marker for ink lines
Clear top coat: KlassKote 2 part epoxy paint, airbrushed
This was my first time with the Duplicolor lacquer. It went on beautifully, but blushed a bit due to the heat and humidity. Burnishing lightly with 0000 steel wool took care of it. It was also my first time to do ink lines.
