I powder coat my cars and was thinking of doing a couple of my antique briggs engines. Is this desirable in the hobby? I just purchased a lot of antique exhaust from antique small engine and was going to PC them Silver, high temp engine manifold silver...It will stay new looking till 450 degrees, I dont think small engines come close to 450 but could use a IR thermometer to check. Is powder coat appreciated or frowned upon in the hobby. BTW I have PC for a number of show cars, so the results are near perfect!
