Well, I had no problem finding thermal compound at Radio Shack, but finding 100% isopropyl alcohol is a challenge. I found some at http://www.tselectronic.com/shop/product/MG-Chemicals-824-99.953--Pure-Anhydrous-Isopropyl-Alcohol-%28Liquid%29/346 but I don't know whether I should bother, but use 91% instead (found everywhere, and inexpensive). Does anyone have suggestions on this?
