I've got some stuff I got cheap and have been cleaning things, repairing a couple bad threads, etc. An example is a Moroso dry sump tank that I got on Ebay for $30 and did some minor repairs and now have a tank that looks like a just slightly used unit. The question now is to keep it clean and make it easier to clean while in use, is it better to powdercoat it, or should I leave it bare? I don't figure that it has much value uncoated as to heat dissipation being that it will be mounted in a compartment where it won't get much air, and in that area I'd probably be better off with a cooler anyway. What do you guys do? Salt on the bare aluminum would not be good, powder would help preserve it. Is there any reason that I'm not thinking of that coating it would cause problems?
