Thanks for the info. I think you are right about the die grinder. I think it is spinning too fast. I will try the drill and see what happens.
You don't need too much compound on the wheels when you are cutting, right? I am using a different wheel for a different compound.. of course.
What about technique .. is there a 'pattern' to follow?
I will try the process again with lower speeds ..
Do you have any experience with the high-lustre aluminum compound? It's hard to get the compound into the loose cotton wheel.
Also, after the black, I use the brown, but when using the brown after the black, the wheel turns black .. and makes the brown compound turn black when I apply more to the wheel .. is this normal?
