Affordable Powder Coating Co

I went here to have some older cast parts powder coated. And they stated it might out gas. Well after they did it, it look like crap and they just expected me to take it. I said no and they redid it and it came out as bad or worst. Finally talked to the owner and he said he would try and prebake it to get the impurities out. And the third time it came out fine. After my own reserch I found they should have done this the first time. What upset me is I spend over a 100.00 bucks to get this done and when it looked worst then when it started, they expected me to just deal with it, like they had better stuff to do.
