Wow, you guys are awesome. Thanks for the info; much obliged. And you had both guessed correctly: I'm working on an LT1 intake manifold. The reason I'm looking into powder coating it are for two reasons. (1) Because the casting of this manifold leaves MUCH to be desired. In the process of sanding it down I ran into many areas where air bubbles in the casting surfaced. More sanding only yielded,(you guessed it), more air bubbles. (2) I had considered having this thing triple chrome plated, but the more I think about how much copper will need to be applied to fill in the air pockets, the more I think this manifold would get hot enough to boil liquid nitrogen at the North Pole in the middle of February. So I think I'm gonna bite the bullet and purchase some of that Lab-Metal Putty to fill in the air bubbles, then get some of that Reflectra Chrome stuff and go to town. I'll be sure to upload some pics of the finished product when it's complete. Thanks again guys.
