The problems with re paints are... you have to strip the frame. You might have to chase some of the threads when you get the frame back due to paint in the threads.
Some (many) repaints have paint that is not as strong as the original and scratches very easy.
There are many good repainters out there too. If the paint is done properly it is strong or stronger than the original. Do your homework. Ask to talk to customers before you get the work done. Or go to a recommended painter from a happy cyclist.
There must be some people on this forum that can address the problem of long lasting strong paint from experience.
Seely?............. Long lasting? scratches? From who?
I have painted a couple of my own frames just to learn and enjoy it. The paint I used was easy to scratch, I did not bake it or do anything special. I know about the problem so it's OK for me on two of my nice looking but practically free beater bikes.
I would not recommend this for a favorite nice bike.
