Friends that are in the heavy equipment industry uses the white 3M disc for clean up on Aluminum surfaces as well. They also use the 3M yellow discs to polish hydraulic cylinders, it removes small burrs. Thank you to my friends Chuck, Cruz, and Clint for the extra tips.

it does clean up nice but arent those score marks from using the tool? it looks like they werent there before.

[@713jtmechanic8]

It is possible that the disc can damage the surface, if one stays on one spot too long or applies to much pressure. This is a delicate procedure using the plastic disc. The white plastic disc is the softest. Great question extorter. 😊👍

GM recommends not using them. I didn't see the recommendations against them until I had already used them. The bit of gasket I was trying to remove was extremely hard to get to so it was hard to scrape off with a razor blade.

They recommend not using them because of the dust the disk creates when it wears down. I would take the risk if you block off the passages, seal the cylinders with grease, and change the oil afterwards.
