Rear Fender Questions

[coxy]

autosol is now making aluminum polish that comes in a silver tube .autosol is not the best polish that i have used there used to be a polish called waterberrys buffing compound that worked on every type of finish and great result every time but i haven't been able to find anymore .also liquid reflection but if you find this do not use it on black chrome or get it in your eye
sorry about the to much information

My'67 GTR with 3800 miles showing on the clock does not have undercoated fenders. I've owned many bikes over the past 45 years, and have never seen this on any of them, nor have I ever heard of it being done by any OEM. Just my 2 shilling's worth.
