We have a Santana Sovereign (aluminum frame) that is 2 years old. It is our pride and joy so we only ride it on special occasions (tandem rallies, club rides and our long Sat. ride). It only gets ridden once and sometimes twice a week. I baby it and try to keep it clean and in top condition.
When we purchased the bike there was a small (about the size of a dime) imperfection in the paint on the underside of the frame by one of the pump brackets. At first we didn't think anything of it. When we rode the bike we didn't even know it was there. However, during the course of the past two years it has grown and today I took a close look at it. I scratched at it with my fingernail and some of the paint flaked off and under it was this white powdery substance. Living in Florida we recognized it as oxidizing aluminum. It's like a cancer. If something isn't done it will continuie to ruin the paint on our bike. I've included a couple of pictures of the situation so you get a better idea of what's going on.
Any suggestions as to what we should do? Is there any use in contacting Santana about the situation? Any ideas on refinishing that part of the frame? Whatever ideas you have will be greatly appreciated. Thanks in advance!
