When you cure the part with too much powder it can cause orange peel effect, it can sag, and you can get pinholes.
If you're talking about thickness in the number of cured coats you'll eventually reach a point where the insulating properties of the previous coats won't allow for a good ground resulting in back ionization. It may also cause problems when re-assembling parts.

I'm sure I forgot something Hopefully others will offer up their .02

I always thought too LITTLE powder caused orange peel?

Re: Am I too Thick?

There are many reasons to obey the laws of mil thickness...

1. Orange peel
2. Salt spray
3. Color
4. Adhesion
5. Because they said so

Also, when spraying metallics it is very important to follow the recommended mil thickness to get the best results ! This also apply's to the clears !

Slow down and read the whole post, not just the title. Seriously though, there are directions on all powders that I am aware of that state "needs at least _____ mils thickness. Are there any good rules to follow for " Hey idiot, dont go over _______ mils thick?

I dont guage thickness now, and dont know if I am going to start, I know the way I coat everything twice and thrice there is plenty of thickness, I was wondering where the (oh crap its getting to thick) starts to come into play. Or is there a such a thing?

Thanks,
