Original Krylon, not the plastic safe version, is listed as an enamel but the solvents in it are more like a lacquer. It will attack a lot of paints, especially fresh paint.
Dullcote is also a lacquer. I have had it attack decals that were a week old when sprayed from a rattle can. Using it from an airbrush I can apply lighter coats, which dry faster and flatter and not had it lift any paint or lettering.
You read a lot of recommendations for various products on the forum but not so much how to use it. How to use it is just as important as what to use.
