Sealing Oil Pan Red Permatex Vs. Ultra Grey Options

[rave2n]

Just curious for some insight before I seal these oil pans this evening.

I've purchased high temp red permatex for the oil pans, but I've been reading around to use the Ultra Grey. No one seems to give a good reason behind such, so I figured I'd inquire with you folks.

Lets here some reasoning!

Please don't say use Toyota FIPG or whatever it is.

(a) Remove any old packing (FIPG) material and be
careful not to drop any oil on the contact surfaces of
the oil pan and cylinder block.
• Using a razor blade and gasket scraper, remove all
the old packing (FIPG) material from the gasket
surfaces and sealing groove.
• Thoroughly clean all components to remove all
the loose material.
• Using a non–residue solvent, clean both sealing
surfaces.
NOTICE: Do not use a solvent which will affect the
painted surfaces.

illustration.
