I saw on one of the many gasket posts, where someone posted a picture of a wire 3M brush that works as an attachment to a drill. I searched several of the gasket posts but couldn't find the picture that I was looking for.
If that poster or someone else could post it, I would really appreciate. I have a friend who works at 3M and they have a company store. He is replacing my gasket also, so he can buy the brush at a big discount.
