The folks at 66AutoColor did an excellent paint match for my 750!

I had the bike repainted, and the painter (not me) picked GM's 2-part epoxy, in gold. While I wasn't happy about the color choice (I had told him "anything but gold, preferably Blue-Green or a blue") it was in trade for something else. The paint itself, however, has been incredibly durable, surviving over 80k miles with frequent tank bags and the usual gasoline spills and abuse. The side covers finally broke from age and I asked the folks at 66 Auto Color to try to match this old paint, sent them a piece of the side cover. The match is PERFECT, even to the gloss.
I'd recommend them if you're trying to match something and can send them a sample. Nice folks, good job!
