I recently painted an aluminum bike. I put the primer down, then the paint color, then a clear coat. I did all the sanding and everything that goes along with painting the bike. After letting it dry for appox a week after finishing the paint, I clamped it down on the bike stand. When I took the frame off the stand the clamp and dug into the paint. Anyone know why this is happening and how I can fix it so it doesn't continue to happen??
I'm no expert but having repaired the paint on several cars, I would think that a week from the application of the last coat should be long enough for the paint to cure if it was applied correctly. That said I would assume one of two things:
- You are clamping the frame much to tightly. I had this problem when I first bought my stand. Buying a carbon bike cured me.
- The application of the paint was too hasty. Possibly the primer or one of the early coats of paint did not have time to cure and adhere as it should. This would allow subsequent layers to shift when pressure is applied.
