Steve, the only cleaner I use is rubbing alchohol and that is rare. I only use cleaner (alcohol) when I can't give the surface a fresh grind to clean off anything stuck on there. I figure there isn't a much cleaner surface than a freshly ground piece of metal.
I glued up a couple more things today. One I used was called PC-7, a 2 part paste epoxy. It comes in a little cans like 1/2 pints of paint or that wood putty used to come in. The colors look like and mix up to the color of JB Weld but with the thickness of plumbers putty except it is a lot tackier. This stuff is very thick and looks like it would go on like laying a welding bead. I knew right away it was not appropriate for handles or even sealing bolsters since it is too thick and would not squeeze out. It is very interesting stuff and I was immediately looking around for *something* to use it on. I settled for glueing up a few test pieces of metal, 1 set sand blasted, 1 set roughed up with fresh 36 grit, 1 set just as it came. I hope to test which surface prep will provide more tooth, the sand blasted or the 36 grit, the plain will give me some idea to compare to. When you need to epoxy something together with a mechanical lock that is the consistancy of thick toothpaste, this is the stuff. If epoxy can be cool, this is cool beans. Won't work worth a #### for knives, but it looks fun to use on something.
