So I just picked up a newer gen Mark 8 oil pan, I want to get it powdercoated on just the bottom surface to protect it from rusting out, etc. I have heard that powder coating will melt the solder from joints in most oil pans when in the oven. However I'm fairly certain there are not plastic bits in MK8 pans, and they are actually fully welded, not soldered. Let me know what you guys think. Anybody know what ford's factory means of coating it was?
