2nd coat problems
I am new to powder coating and I am having trouble on 2nd coats on aluminum parts...
more specifically I am trying to do a valve cover.. I tried to do a metalic silver first, then the lolipop blue 2nd.. the first coat always looks good, but the second coat looks terrible...
I tried over super chrome as well, and I tried with steel pipe...
the second coat looks all washed out, like it wouldnt stick in some places, or like it just ran off?
I did part of a mandrel bent ss pipe for practice and on the inside of the bend it looked pretty good, but on the out side the blue is terrible... it didnt cover at all.. at the same time (cured at the same time and everything) I did a similar pipe with no base, just the blue on top of the steel, and that looked great...
what is the problem with two coats?
TIA
