Re: ah WTH ?? candy lime green

In your preparation explanation, I noted you never mentioned off/out gassing the part. If you didn't off/out gas the part, this may be the reasoning behind this "bumps". When you degreased and cleaned the part it probably left contaminants in the metal, then when you heated the part up to either shoot or cure, the pores in the metal opened thus releasing those contaminants and damaging the powder from inside out.

I could be wrong, but I hope this sheds a little light.

How did the powder look before you baked it?? did it look perfect with good coverage?? and not until baking that you saw the isues?

Re: ah WTH ?? candy lime green

Did you use anything on the part after the base coat and before the application of the candy?

Nothing was used between coats? should there have been something used?

I did not outgas the metal, I did another part in matte black and it didnt do this, and it only appears to be when i apply the candy or top coat that this problem crops up. The base coats go down smooth, and look good, but the top coat falls apart.

The coverage was even, it was a little light around the sharp edges, but there was not these HORRID looking holes in the powder before going into the oven? these only cropped up after baking the part?

It didn't click to me the first time I read your post, that the base came out good. Hmm, odd. Well, I am sure someone will come up with some sort of reasoning or solution. Good luck!

Re: ah WTH ?? candy lime green

looks similar to undercure on the base coat, was it fully cured and not half cured like dormants?

Re: ah WTH ?? candy lime green

Ok guys I need to know what went wrong? These are just some little sample panels I was trying to shoot to see what the candy lime green looked like. Well after 6 trys I said F it. these were just blank steel templates, I degreased them and also used brake parts cleaner on them after degreasing to make sure they were clean. I applied my base, I used extreme chrome, mirror white, gray metallic, and silver on several of pieces. The base coat would come out fine, but the candy coat did this everytime(look at pictures). What is causing this? I am using a POS HF gun also if that helps any. sorry for the crappy picture camera phones arent all that great. also when i try to do a candy coat over a base, i cant get powder adhesion around the edges its like it repels powder. I tried putting the candy coat on when the part reached 150 but still didnt seem to work.

Do you have a pic of what the part looks like before it went in the oven for curing ?

I knew i should have snapped a picture of the base coat before i applied the candy. This happened with EVERY base coat i used also. everything is fine till the candy color.

Re: ah WTH ?? candy lime green

Is your oven clean? I ask because that looks like contamination of some sort. Since you say your base coat looks good I would rule out the air/gun issue. If your oven is dirty/greasy is could be spreading grease or something on top of your base coat. Also check you cure time and temps. You should be starting your timer when the part reaches temp. If you're starting the timer when you load the parts your cure time will be wrong.
