Hey Everyone,

Thanks in advance for your time. Been restoring a 1987 Trek 2500 with full Dura-Ace for my brother's birthday.

The carbon tubes has some bubbling near the lugs just under the clear coat.

I have the clear sanded off now down to the fibers...was careful not to bite into them.

Do you think this is repairable?  What kind of clear coat should i use...lacquer or enamel?  Any specific recommendations?

Thanks,
Erik
