I use the liquid Gasketcinch brand of gasket adhesive, sealer
I'm sure Jegs and Summit sells them in different size of cans, I buy the littlest cans and use it as needed
The bigger containers last forever and will usually start to get thicker the longer it sits on the shelfs once you open them
Follow the instructions to success, no more having to scrape gaskets off after using that really good stuff instead of using the "Right Stuff"
