Need help with solution for mirror finish repair!

2006

I am repairing a pharmaceutical product container that was damaged during transport. The entire inside of the container is mirror finished. Due to welding on the container, I had to slightly grind the surface in four places. The largest blemish of the four is approximately fist size. What chemicals, tools, and procedures do you offer for this repair?

Thanks,
D.J.

First of two simultaneous responses --

Look for a mold polisher in your area or for the tools used by them. Different grit dressing stones (220 to 600), sandpapers (220 to 1500) and polishing pastes (diamond or aluminum oxide) that are used with cloth or felt bobs and high speed rotary tools.

It would help if you tell us what material is the container!
