I used the gaskets that came with the MP windage tray.They haev been on for 10 years and I carry 70 to 80 PSI.I didnt use the tray I used the Milidon tray.Those gaskets suprised me they sealed so good.I use 3M weather strip adhesive to attach them to the tray when I install it under the car.Other than that my gaskets go on dry.Silicone and cork dont mix.Rocky
