Yeah, I got my own share of issue with enclosures... I once used the infamous Tayda silver power coated enclosure that scratches just by looking at it. I tried to buff the scratch out with just coton and car compound and the whole things started turning black. I dissolved the whole powder coat in acetone down to bare metal. Then repainted it with silver Rustoleum Painter's touch 2 X paint and a clear of the same line. Did a pretty good job.Whole dang thing puckered up, I started sanding it back to start over then said "F this.....", and that's the way I left it
