[TR] Proper gasket installation

[Mark J Bradakis]

I should probably know the exact part number since I have
been using the stuff for years.  Permatex makes this spray
on sealant, red and sticky, that works quite well for a
number of gasket applications.  Maybe 99H??  They also
make a good gasket remover in a spray can that looks almost
exactly like the can of sealant.  Luckily I never got them mixed
up when wrenching.
