Yea, yo, the paeco is reuseable, man it oughta be for what it cost. I want to say it is like 200 or 250 but if it seals as well as they claim it would be a bargain for the high compression crowd. Also it comes in two thicknesses, .030 and .060. So a little over 1mm and a little over 2mm. Now that I think about it I believe the catalog says that as long as the deck and head are perfectly flat you need no sealer on it.
