Do you put sealer on the bolt threads? Any special tightening sequence? Basically want to know your secrets.

Thank you in advance.

I'm no expert but have done a few pan gaskets in my life. #1 is to make sure the pan is straight! People OVER TORQUE PANS AND VALVE COVERS! When they over-torque they distort the sheet metal at the bolt holes.
Secondly, ensure all old gasket material/adhesive/rtv/ whatever is removed prior to installing new Fel pro gasket with no rtv/adhesive/whatever. The only way I would use anything on the gasket is in a vertical application where you need to hold the gasket in place to get the bolts started.
