I usually have no problems blasting paint off in my cabinet using black diamond media. I have found that paint stripper is just about useless lately though. I used to be able to find a stripper called Mar-Hyde Tal-Strip locally and that stuff worked great. However, now all I can find locally is Rustoleum and Klen Strip which takes 15 applications to make any kind of dent.

Before I blast, I mask off all bearing/gasket surfaces with a layer of painters tape and 2 layers of duct tape. It keeps them protected from the media, but masking everything off is pretty time consuming.
