pretreament
i have a question, on the caswell website for the Epoxy powders. For the pretreatment for that they say to use a zinc phosphate for pretreament. Now for that they say to use use the degreaser too. Now what i heard is you glass bead it first, then power wash it and it should be good. Can someone tell me what the Correct steps are for pretreating it? I want the most simplest but effectivly way possible. I dont want to have to buy 5 chemicals and pretreat it. I would be powder coating aluminum.
