Well one day I finally had the time on my hands and went to the store and bought Zip-Strip and MAAS polish creme. That same day I did a little patch, just to test it out. And left the horn alone for a few days. Then for about 3 days, a couple hours a day, I delaquer part by part. I used an old tooth brush and that did a way better job than a cloth. It took me a total of 5 days to due it all. Although I could of done it in 3 or 4 days! But, just yestday I did the inside part of the bell, the 1st, 2nd, 3rd, and main slides. So they might be shinnier than the rest of the trumpet. But I can definatly see it change color! I got to say, that was a pretty hard task!!! I ended up taking very close to 100% of laquer off! All of these pictures are during and after the delaquering... Under my leadpipe their are these corrosion dots. How did I get them? And how would I get rid of them?
