It is a straight forward job - cleanliness and prep are key. Remove ALL of the old sealer, brake clean it all very well and I have actually used "The Right Stuff" as a substitute sealer and works the same. Be sure to run a good clean bead all the way around but do not make it so wide it squishes out and falls in the pan. Slightly tighten the bolts in a criss cross manner to evenly bring the pan up. Wait about 10 mins and then finish torquing to spec. Also - read the sealer directions closely and follow.
