Classic & Vintage - One of those annoying questions-

Sorry brothers and sisters, but I couldn't find it via search, maybe I'm just picking the wrong terms.

I got a fantastic strip/prep/powdercoat of a frame and fork with a candy color for $120, the lugs are clean and it looks very much like paint, I'm wholly impressed, but pictures won't show for a few weeks... I have my reasons-

But I have a questions. The fantastic job aside, there is just a little bit of powdercoat that goes along the edge of my BB shell that keeps me from getting the bottom bracket cups back on, it's negligibly small, but still renders the part disfunctional.

And I asked the PC'er to mask the downtube shifter bosses but told him not to mask the square parts... I'm an idiot for that...

Basically, I need to strip off tiny amounts of powdercoat, maybe with a small brush or something, and I'm not too sure how to go about doing that, and the internet is failing to give me good information.

Are there any products suited for this?

Sorry this question is kind of dumb,

A small file and some emery paper? Mask it with duct tape and then go to work to take down the power. First test fit the shifter backing plate to make sure you HAVE to remove some of the PC.

Yep, test-fitted it, it wouldn't fit!
I thought it'd be fine (and look better,) so I told the PC'er not to mask it, and now the plate won't fit. I considered just making the hole in the plate a little bigger, but I'd rather not ruin one more set of old shift levers...

And then I still have that good ol' bottom bracket problem. Maybe Jasco?

Take the frame into any decent bike shop and they should be able to face the edges and chase the threads--if there's overspray there as well--for a minimal charge; they can do the head tube faces as well if you run into problems there.
