It's holding up pretty well. It's chipping/flaking off the crank, but I couldn't find the self-etching primer for that so the primer itself didn't really have any good way to bond to the crankset. On the frame, I've only got one scratch so far and no chips or flakes. The scratch was from chaining up to a street sign yesterday. Overall I think it's at least as durable as the factory paint job. Key with this stuff seems to be to do proper surface prep, priming, multiple coats, and then letting everything cure properly so it can harden like it's supposed to (I let it cure for about a week before I started riding it again).

Powder-coat would, of course, be more durable, but for a total investment of about $10 I have to say I am VERY pleased.
