Re: HARLEYDAD
Per your PM,
Also when drying the part get yourself a little hand torch to dry it off and get any lint that was left behind.
To me it is hard to see in the pictures what those marks are. Did this happen at ALL on your test panel? If so you might have some issues with water or oil in the air hose line. Also it could be left on solvent from your prep. Try a test panel with no prep and if it turns out with no issues then you know the culprit. If the test panel shows issues then its your air line (I think). Process of elimination 1 item at a time. Test panels can be very worthy.
Here are some trouble shooting guides to read through.Comment

Re: HARLEYDAD
ok so it was the same except for the stripper
what i meant to say was , same batch ,same powder,etc....
i do use a propane torch when i hang the pieces right before i shoot them.
after stripping i use a pressure washer to remove the stripper, i thought that would be sufficient to remove it
the fender i'm gonna do today was new,waiting for the problem fender to come out of the tank, will probably shoot tommorow.Comment

These are the questions I would be looking to answer. If they are unclear I can talk to you on the phone to see if we can come up with a plan to test.
If you did not strip the panels or prep them and they have the spots on them. I would be looking at your air compressor lines and do a quick test. Napkin test (You should do this anyways if you have not already)
Switch to an air blower on your air hose. Get a paper towel and fold it until you get about a 3X3 inch square. Hold it on the tip of the air blower or about 1 inch away. Hold the trigger down for about 1 minute. Check the napkin for dampness or discoloration.Comment

Re: HARLEYDAD
Ok,
Then I would be leaning towards what HD said. No need for the Denatured. You can skip that step if you want.Comment

ORIGINAL FENDER; CYBERSOLVE,PRESSURE WASH,AO BLAST,RINSE,SURCOAT,RINSE,DRY,PROPANE TORCH,SHOOT
NEW FENDER;AO BLAST,RINSE,SURCOAT,RINSE,DRY,PROPANE TORCH,SHOOT
MAYBE A HEAT CYCLE FOR THE ORIGINAL FENDER BETWEEN THE WASH AND BLAST?Comment

O.K. now, what did we learn?
no need for alcohol{on the part after surcoat}
mirror black does NOT need to be 4mils thick,(1.2-1.8)
outgas,outgas,outgas,cook that sucker good
when you think it's smooth, sand some more
lower temp,longer time
make sure you have clean media
make sure you have clean air
only work when you feel like it
you don't always need 100kvComment
