For me it was Harley saddlebags. One day at the carwash, the clear blew off! I had accidentally skipped a step, and told the owner it could happen...just bring it back if it does. He was understanding, and knew I would stand behind it, since I had done other jobs for him. (No, they did not fail) :-)

Today I am very careful, and guarantee my work for as long as they own it.....no time limit.
