Thanks for all the comments. This has really helped me plan a strategy
RENDEGADE.
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!
Definatly too much paint, in spots. This is patialy due to inability to get the gun adusted properly, and being too damn cheep to waste paint on testing. Another issue may have been with the mixture. I used dt870 reducer on the first two colors (Yellow-red).
When I went to mix the blue, it seemed that the temp. had gone up, so I used dt885.When I checked the temp in my car, I saw that it was cooler than I had thought is was. This is another important lesson. DON'T GUESS ON THE TEMPERATURE.

I think Rendegade pretty much covered the probable causes. I've used PPG Concept on at least a half dozen ships with very good results.
A word of caution about this type of paint- unless you have an air fed respirator, do it outside. This stuff can cause permanent lung
damage. Good Luck.
I use a good full face respirator in a garage with the door open. Unfortunatly, outdoors is not an option. I live in a condo-complex, and I am hoping that some association nazi doesn't say anything about using the garage for something other than parking. Forced air would be good, but it is expensive.
