    I’m sure this topic has been covered extensively before.

     

    I’ve managed to acquire a vintage carbon bike with 105 (down tube shifters) but the frame has either been rattle can painted or hammerited! I’ve read plenty about stripping a normal carbon frame but wondered if anybody had any particular advise on how to take the frame back to carbon, safely.

     

    Thanks in advance.

    Agree with comments above – wet n dry back to a sound smooth surface, no need to go all the way down.

    I wouldn’t even bother painting it.

    Be very careful. I did this to a black-painted Trek that had cracked (and Trek’ s sh*t warranty didn’t cover) and couldn’t tell if I was through the paint until I was most of the way through the carbon. I would echo the comments saying don’t try and take it down to the carbon as you’ll never achieve the pre-paint bare carbon finish and will probably bugger the frame.

    Bear in mind there will

    Bear in mind there will probably be a lot of filler inder the paint, where the trapped air from the mould left voids that needed to be filled before painting. It’ll look like big white, green or yellow patches that aren’t paint, so don’t try to sand them out

    Wet & dry and lots of elbow grease, be patient don’t try to do it all in a day. By using W&D you can keep an eye on how far your progressing and won’t bite into the frame which could compromise your safety.

    Fine sandpaper should do it?

    Fine sandpaper should do it? That’s what my bodywork guy seemed to suggest for my car’s carbon bonnet. Presumably it’s just a case of sanding back to the carbon lacquer?
