American Metal Cleaning wasn't very careful with my 70 bee fenders when I had them dipped years ago (lots of new dents). Just a word of caution.
Also I heard you need to have a quote in writting and what they are doing as the bill likes to get added to in the end without notice.
The guy will tell you one price and his wife will charge you another higher one.

I haven't dealt with them for probably 10 years but from a couple friends I heard this other stuff.
