Getting ready to order my brush research flex hone and want to make sure I get the correct one or ones if needed. I know its the 105mm or 4 1/8" but what grit or grits? 180, 240, 320? Aluminum oxide or silica carbide? Only doing a surface prep for new rings, cylinders are all dimensionally good, just taking the glaze off. Get conflicting info in my research and its always directed towards gas engines...
