Not really - in the case of a failed clearcoat you need to take it down to bare metal and start all over again from self-etching primer or epoxy primer.

In your case, the bike is bare, clearcoated aluminum. I'd use a new prep brush for aluminum and call a local auto body supply shop and ask them for Spray Max 2K spray clearcoat - it's a 2-part urethane clearcoat that activates in the can. If you have a spray gun(preferably HVLP) and a stout air compressor to drive it, you can use a automotive clear coat. PPG, DuPont, Glasurit, Sikkens - they'll all work well. Just be sure to WEAR RESPIRATORY PROTECTION, isocyanates are NASTY and TOXIC!
