Review on Three Bond Engine Silcone Gasket by Christian Poojary

Very, very good stuff. I used it to seal a BMW engine which I rebuilt despite BMW's recommendation not to use sealant. I don't think they have much to talk about given how prone their engines are to losing oil. After the restoration not a drop has flowed in a year of car ownership. Tip: Clean the surfaces very well with acetone or something similar. Then apply a very THIN layer. You can use a small brush to apply a nice even layer. You don't want to smudge it. It should be as thin as possible. I also recommend leaving the area a few days before use if possible. It's not the fastest drying material, but that was the least of my worries.
