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.

The going crazy with it is where the finger method comes in. Lay a fat bead of rtv and smooth it over the entire gasket surface. I guess Ive always used my finger to spread it and never thought twice about it till now.

Yeah and gray is good stuff. I usually use gray in places under alot of stress, like bearing caps or the rear main seal. I usually use black for valve covers and oilpans because its supposed to hold up to oil the best, but Im certain that both types meet and exceed the requirements for an oil pan. Cant spend too much time overanalyzing things.

Yea in the end, I used the black...considering it was the same price as grey, and has better oil resistance...figured why the heck not really.

I did end up using my finger to spread it, just wasn't comfortable with the dropping a bead concept. I wanted 100% sure all surfaces got the goo =P
