what do you use to polish the shell?
coley!...
I'm going to assume.. ( and that is a word I normally HATE to use! LOL! ) .. that you are asking about my drum, yes? If so, here's a thumbnail sketch as to what/how I did it:
This drum being a 1982 was COMPLETELY tarnished when I found it.. ( the bronze turns "copper" like an old Lincoln penny ) .. and we all know that OEM bronze should be like brass/gold in color. PLUS, and this is the killer part: Ludwig CLEARED these shells with something, which I thought might have been clear lacquer, but that didn't seem accurate as it was a BEAR to get off so I could actually polish the shell back to original. I still don't know what was on mine for a "clear", but there was something there. The funny thing is, THAT was supposed to help in preventing the tarnish/finger prints, etc. Maybe it did work, for a while anyway, but the drum IS 30 years old now. Anyway...
Nothing I tried by hand worked... none of my tricks... nothing. I just couldn't get through to the tarnish so I could polish it back. I had to go to other methods, and that is the result you see here. I sent the drum out to a professional metal polisher that specialized in brass, bronze, and copper. They used a special compound/rouge in conjunction with a buffing wheel to cut through the tarnish. The speed and friction/heat of the wheel in concert with the rouge/compound did the trick! The shell was returned to OEM with absolutely NO DAMAGE, burns, scratching, etc. The shell was perfect! Then...
They sprayed on a waterbourne "clear" in a semi gloss finish with a UV inhibitor which will HOLD the drum shell from tarnishing for decades. Paint/clear technology has indeed changed since Ludwig built this drum back in 1982, and that is for the better in this case! There were no waterbourne products back in 1982 of course. The results are as you see here... gorgeous!
It was worth it to me to have done, especially after I had exhausted all the methods that have worked for me in the past. This one was TOUGH! Goes without saying that I completely disassembled the drum including badge/grommet, which all had to be put back after buffing/polishing. Everything on the drum is original as it left the Ludwig factory.
Hope this was of some help/information for you!
