Hey guys i have a ggts #620. I am told this is an aluminum without nickel plating but it is developing black marks on it like some sort of nickel plating is coming off it. Is there a chance that my 620 is coated? If not does anyone else have any black marks forming on theirs? Thanks for any help. Here is a pic View image: IMG 4334 2. I can post more if need be. The marks are not raised. I have been the only owner and it has been polished only 2 times.
You must get those black marks out before they set into the metal and pit. Possibly your body chemistry has changed and now when you touch alumium it will created the black marks.
I would think it would need aluminum cleaner first if polishing would not rid them, followed by sharkhide alumium polish.
Sharkhide
Send a pic to the company and see what they say.
Also if this is going to happen to you, I would consider selling it to someone else. Black spot problems will only destroy the GG, unless you are only going to keep it to look at. If mine ever started doing that I would sell them, meaning I have an alumium and 2 nickles. Both finishes are known to do that to some people depending on chemistry of their skin.
