bleed through is mainly caused by four things.

1. too much paint

2 paint too thin (it can be thin but don't put too much on, ref rule 1!)

3 crappy tape

4 poor subsrate prep.


too much paint, is the big killer, so just take it easy on the first few sprays till it builds up. less paint more often.

crappy tape is one that is my personal bugbear. See if you can get some 3m fineline tape, and mask out your trim with that, and then use your crappy tape to attach skirts of paper (I've shied away from newpaper after it left grey spots on my last job I didn't find till I'd sprayed clear)

4. did you spray the base coat and then go straight to masking? you've gotta have a really good gloss off the gun if you're planning to do this. if the base coat is orange peeled, then you're a prime candidate for bleed through. I usually clear coat so I'll hit the base coat and any non metallics with some 800 between coats. I don't hit the metallics as they tend to go dull when cleared for moi.



as for the gun, do you have constant pressure, i.e. a reg?


Pinholes? you need more time spent looking at the primer my friend!
