Yes I've seen that data sheet. At some point, I had printed and followed "Restoration Shop" (I think TCP Global) for ratio of their acrylic enamel, even though I used ALK 200. I also use other brands for the high gloss acrylic enamel hardner and reducer. It all laid down shiny, just orange peeled, aside from some curvy areas acceptably smooth. I have not had any other issues with the paint thus far.
Good to know on the powder coat issue. I think I'll go ahead with a high quality automotive paint. I think Napa carries with built in clear (not sure how that works).
