Thanks for the info! I'll be using it for those hard to break screws. I just don't know which grit to get. Anyone have any hints? I've been using some generic stuff from someone else's tool box with no label on it, so I'm not sure how coarse it is.

I would ask someone at your nearest auto part store, granted they havnt been replaced with morons like at radio shack. From personal experience, a torch usually breaks bolts for me pretty well, as for screws, im not so sure. I remember working with my dad trying to get a lug off our car, we broke 3 Craftsman sockets, and 2 Craftsman wrenches. Turns out all we needed to do was use alittle heat and it usually loostens bolts up.

If you have access to Liquid dye penetrant (LPI) gear or know someone in the NDI/NDT trades. Use the flourescent penetrant as a lube on seized hardware. It is designed to flow into the smallest of cracks, so it really works as a thread lube.

I think that most of your respondents don't understand that you are using the lapping compound on the the end of your apex tip to get a better grip on the screw heads. While their suggestions for heat and penetrant are good ideas, they just aren't applicable to your situation.
I'm holding a 16 oz. can of 600 grit. Part number is 4A 51804. The side of the can lists grits from 36 up to 1200. 400, 500, and 600 are listed as very fine.
800, 1000, and 1200 are extremely fine. I would suggest something in the 400 grit area.
