Re: Actual Blown Headgasket
The only reason most of us use wet paper is it doesn't plug up as quickly as dry paper does. With the paper very wet it sticks to the glass well enough you don't need to fasten it down. I generally use 220 then 400. I do a little polishing but just to the combustion chamber with Mothers polish. I think it helps keep carbon from sticking as quickly but it's probably not really doing anything. I use a piece of scrap 1/4" thick glass from a local glass place. Thinner glass can be flexed.
