Nathan, Don and Greg -
Thanks for the prompt and helpful responses. Now it's clear why I should have been more descriptive of the repairs I'm asking about.
I don't have any that require filling, filing or sanding, just a few TINY marks left behind by Tamiya Extra Thin at the join lines, when cementing at component bonding time. Not the kind where excess cement and melted plastic squeeze out the join line, just a miniscule cement dab that flowed away from the surfaces and left what looks like a tiny "wet mark."
I found I really don't need to repaint as yet, just a light sweep with some very fine polishing pad strokes and the cement mark disappears, even before clear coat. If I do run into something a bit more severe, then it will require paint repair.
In that case I feel somewhat confident, that the touchup method with just light surface prep and like Don says, some very light passes with the AB should do the trick. If I do run into that, I'll post the process and results.
Thanks again guy's, very helpful. You're a good bunch'a fella's.
