I second the Permatex Ultra Black - although the reason I use it (versus
other brands or whatever) is that it's stocked at my local Farm &
Fleet. I use the Permatex copper colored for other surfaces (like front
plate to front of engine) but ultra black for pan and timing cover
gasket. The Ultra Black is more durable / harder to remove than the
ultra copper. THIN layer on both sides of gasket so it doesn't ooze
into the engine and gum up the works as Alex describes.
I also beat down any bolt hole dimples (due to previous over
tightening). If anything, having the bolt hole slightly concave on the
sealing surface so it can pull back down to flat is preferable to having
it stand proud of the surface. Of course that's better done prior to
the powder coating. :)
