I see on Youtube many airbrush videos where they prime the whole aircraft body then pain t/top coat etc... and they seem to paint all the places where missiles or engines are glued on later. My question is, do these points where attachemnts need to be glued later on have to be sanded to get a good glue bond or does the glue work through the paint layers somehow?
What is the process for gluing parts onto pre-painted surfaces?
Cheers,
