Hi all. I have a paint chip on a carbon fiber frame, say it's about the area of the head of an eraser, but noticeable because the bike is silver, and the chip goes all the way to the dark CF. No damage I'm told, just cosmetic. I have paint that I guess is a close enough match, but here is my question:
I built up the layers of paint slowly, but now that area has a slight bump, and in the light appears dull compared to the rest of the bike. Is there a sand paper with fine enough grit to level out the surface without getting into the unaffected areas? Should I wet sand? And finally, is the touch-up paint (metallic) dull because I didn't use clearcoat? Any advice is welcome. If it matters, the factory paintjob was from Cervelo. Thanks for any help!
