I'm just picking. There's a guy online that "micro polishes" carbs. But he won't tell even the smallest detail about how he does it. he claims his special mix of media is a "trade secret".
However I may use it to make a little resto funds, by offering polished bits, I'm far more intrested in advancing our hobby.
I won't keep my findings secret.
If I go to a car show someday, and find a set of nicley polished carbs, that I find out were done using my info. That's payment in full.
