Quick question (I did search on the forum before but could not find the exact answer) for those that have used back lapping paste before. Which brand do you find the best and where can I buy it? Which grit level should I go for in "normal" maintenance use? Can I use valve grinding paste?
Re the grit level I find that when I use my current lapping paste the centre of the cylinder makes that loverly light grey texture but at both ends the paste wears quickly off. I was thinking a higher grit level initial to help even it out. The cylinder ends are not blunt and still offer a good cut but are maybe not as sharp as the centre.
