Fixing Dust Bumps in Alclad

[Ddms]

I've just finished spraying some smooth "Baby Moon" style hubcaps for my Porsche 356 Speedster, and there are a few dust glitches under the Alclad. She-ite! I must have missed some dirt on the black Alclad-primed surface.

Because of their shape, these caps really need to be perfectly smooth. I can strip and re-spray them, but is there another way to remove the glitches that would be less time-consuming? I was thinking of sanding the spots with 2000 grit and re-spraying with the Alclad II chrome.

Tom ....I think you know, but if it is under the black then sanding it will leave a naked zit......but if on the black sand it smooth and then another shot of alclad...I will keep my fingers crossed for you!!

Thanks. On second thought, I might as well try sanding. The worst that can happen is that I'll have to strip and re-do the two coats. Actually, upon closer examination, I realized that a couple of the "dust spots" are actually sprue attachment points. But I'm going to go for it anyway. I'll make a 2000-grit sanding stick, put on my Optivisor and hit only the problems. Then I'll re-spray the metallic.

Stay tuned.
