anyone ever removed powdercoat from rims? how did you do it? can it be chipped off or does it need to be chemically removed? is there a way to do this with the wheel fully built (without removing and relacing the rim)?

Several ways to remove it. I just googled POWDER COAT REMOVAL and got great answers. Like media(sand) blasting (cheap and for a few parts), thermal (burn it off - upwards of 1200 degrees could cook the rim), thermo-chemical dangerous and toxic), and pure chemical (very toxic).
Ask a local powder coater was he/she does. Use the softest media you can and test clean a tiny patch first.
If you live near a University call and ask if their Craft center or Art school has one, many are open to the public for very small fees. At the University of Oregon it's like 15 for a term for non-students to access the whole craft center loaded with everything from high end sowing machines, a full wood shop, sand blaster, and the usual crafty crap. A greatly untapped resource in many communities!
