My HP41CV just arrived. Cleaning tips?

[Trond]

The wobblyness is a bit odd, as I can't see any problem with any of the rubber feet. I am thinking of applying a couple of thin layer of black acrylic paint on top of the rubber, to increase the thickness just a little (I have fixed plastic things with acrylic paint before, never rubber though). Alternatively I could try to tear the rubber off and reapply it with a thicker layer of glue. What do you think?
