I've found the adhesive/abrasive setup to be extremely harsh - good for hogging off rough areas but not so good for just polishing. The glue is extremely hard after it cures. On a 6 or 8" wheel it will have some give to it though, and grinder's grease will make it less harsh. Put it on a felt bob and you might as well use a stone grinding point, it's that hard. Also, the rpm's can't be too high or you'll have pieces of it flying off (but this is also true of the greaseless compounds). Also, I don't think the loose abrasive comes any finer than 120, although that might've changed.

In other words, it is useful, but in very limited circumstances.

I would say in your application, if the junk is too much for emery compound and a stiff wheel or bob, you'll have to suck it up and make up a bunch of bobs/wheels with the greaseless. BTW, a hair dryer can really speed that up (but it's still a pain in the arse).

Hopefully others will chime in with their experience with Cratex wheels and bobs. I was told by an old pro that they work OK but don't hold up very well...but I have not tried them myself yet.
