Hi @paulbiche,
Anytime you modify something you are risking it. That being said I have never had any issues polishing bars. Proceed at your own risk etc.
I suggest starting with 80 grit emory cloth until the paint or ano is gone. Getting a frame block or some soft jaw to hold your bars in the vice is important.
Always follow the tubes rotation. Not sure how to explain that but don't go up and down the tube like you are using a frame pump, if you know what I mean ;-)
Once all looks silver you use you start polishing. If you want a perfect finish do all the steps of grit. 80 (emory), 120 (emory), 240 (emory), 240 (from here on wet sanding paper cut in strips), 320, 400, 600, 800 and 1000. Then you go to the polishing wheel and buff the shit out of it. When done treat the bars to some Renaissance wax or JADE oil.
For me all these steps only make sense as I have all of the above available at work. I skipped 1000 grit step as we were out of sand paper.
It is costly and it takes a long time but I have been able to do it on less busy days at work and using stuff I have already bought for other projects.
