I have all the detachable body parts ready to sand to paint. I'm working on the main shell and have the all the low spots filled with body putty so it's time to shoot the high build primer.


With the fenders, doors, sunroof and trunk lid I shot two coats of high build, block sanded them with 180 grit and then shot two more coats on them. The orange peel is the real issue since the low and high spots are worked flat.


I'm considering shooting 4 coats on the shell, wet on wet, and wondering if thinning the 4th coat a bit might result in less orange peel.


Can anyone experienced with such nonsense give me advice on whether or not to thin the final coat of high build? Will it help? Will it hurt the final product? Dry time isn't a factor. I don't care how long it takes I just want the car done right.


BTW: I'm using a guide coat to make sure I sand enough and just enough.
