The pictures are old ones on this site, what I have now is bolted together. What is the out come you are looking for? Gloss, smoothness, or durability, any one of which paint will do the same thing. I coated mine because of the finish quality, kinda reminds me of the old ceramic finishes on engines from the teens. Powder will hold up just as well as paint will, both have about the same heat rating.
