flex seal

Hi,
I pulled my intake manifold today to replace the leaky front and rear rubber intake manifold gaskets. i replaced the rubber gaskets with cork ones that i found. i reused the intake gasket since it was a felpro with the blue o rings built in. All went well. i had a thought of wondering if  that flexseal stuff could be used as a gasket spray to help fill some voids. etc.
It is some type of rubber spray and i had a few thoughts like maybe using it to help seal rear end housings etc.
I know that it is for gutters etc. but just food for thought. 
Has anyone used the stuff? I seen it available in clear also. i think.....anyhow...

we joke about that stuff at work all the time to use on these leaky pos 6.4s lol

I don't think I would use it on a engine gas and oil might eat it up and cause more problems I never use the rubber or cork gasket in the front and rear I use a real good bead of RTV let it sit until I can touch it without it sticking to my finger then put the intake on.

that is a good idea with the bead of silicone all the way across. i did put a bead of silicone in the corners. i used the cork ones with a coat of spray adhesive on the cork and i brushed the adhesive on the block. let it tack up then stuck them on. The rubber ones that i took off were split longways in the middle. i will never use the rubber ones again. i remember putting them on carefully and cinching the intake down evenly about 6 months ago but they started leaking when i ran the engine hard.

our news lady did a review on the flexseal and she sprayed a strainer with it then filled it with water later and it held the water.
it is at least that good.
