I have a set of Schrick 280/272 with damaged lobes on exhaust cyl 3 and 6, 6 being the worst. The eroded lobes in question have minimal material shaved. It does catch the nail on 6. I guess I'm asking if they can be salvaged, is there a service where this can be done if anyone knows? These cams were silly money in Canadian slave dollars to my door and just trying to get something back from them.

It's a 2 part formula, one is the cleaner, which is like a thick shaving foam, and the other part is the neutralizer, which makes the foam turn liquid on contact.
The stuff is strong enough to clean without any abresives, I wouldn't put scotchbrite anywhere near my cylinder walls, it is effectively still sandpaper.
Just be cautious you can do more harm than good cleaning the combustion chamber and the top of the pistons if that means a bunch of gunk goes into the ringland area.
Painters tape is your friend...

Yeah, it will be abrasive enough to remove heavy carbon buildup, but shouldn't remove any material from the iron block. You just don't want any of the fibers or loose carbon getting between the piston and rings. If you are going to leave the block and cylinders exposed for an extended period of time, it is good to spray them with WD-40 to keep moisture out; otherwise, they can start to form surface rust.

The older style plugs, which I kept in case I want to revert back, did use a crush washer, but realOEM no longer lists a part number for the crush washer for the E46. You have to go to an older model, like the E31, where they still have it on the diagram funny enough.
