PPG basecoat clear coat question

[BUDDYonRC at aol.com]

 Troy is correct except I opt for no clear coat. 
After I paint the base color I wait overnight then wet sand the entire 
airplane with 2000 grit sandpaper after it is sanded to where the entire surface has 
the same dull appearance and being careful not to sand through I mask and 
paint the trim colors. Wait overnight, remove the mask and sand the trim colors 
to remove all sharp edges along mask lines.
After all is sanded I polish out with 3-M Imperial Hand Glaze #39007
I don't see a good reason to clear coat this system, after it cures for a few 
days acetone wont even phase it.
It is important that if you use a primer use PPG K-36 or equal some primers 
are not fuel proof and hot fuel can damage the finish if it gets under the 
painted surface in places where you drill holes to install engine needle valve 
access or other equipment.
Sanding before you add trim colors removes weight. dust, bugs or anything 
else that fell on the wet paint and also allows you to sand out any runs in the 
paint if you end up with any it also assures a smooth mask surface which will 
minimize run under of the trim colors
