it just says for automotive use. doesn't specify if it can be used near antifreeze. it also doesn't say if it is low volatility or o2 sensor safe, even though it has a picture of a head gasket on the tube.

i just conversed with GE. they say it will break down in constant contact with antifreeze. It won't become friable, but it will lose seal.

man what a pain it is to get it off and on again. if it is the O ring doing most of the sealing, do you think i can get away with just leaving it? the engine block mating surface was fairly pitted and i tried to flatten it with sandpaper but it was still pitted although cleaned as well as i could...

what is a BGB?

my haynes manual says to use rtv to hold the o ring in place, so i guess it did the job to that extent. my concern is the pitting on the engine block. the o ring isn't that thick and i don't know if it can handle the pitting by itself. what would you do?

that's 1 vote for leaving the useless GE garbage silicone in place and counting on the o ring to manage the pitting

GE is ridiculous. they put a picture of a head gasket on the tube and called it Gasket & Seal. for most applications in a car you would think it would need to be either antifreeze resistant or O2 sensor safe. for a head gasket, probably both. this product is neither.
