Three Bond Case Sealant Liquid Gasket

I have been using three bond for years and it is a wonderful product. I never use heavy sealants which you never should for many reasons. Three bond is a light weight however works better than most sealants. It's a bit tricky to work with because it is runny but if you know what your doing it won't be an issue at all. That's one of the great things about three bond. It does not allow gaskets to squeez out the sides. I use this in situations were gaskets call for no sealants.

Great for crank case sealant

This is my second tube of the sealant. The first I bought several years ago, I put together several chainsaws with it. One of the saws was a stihl 029 I bought a 039 kit for it and it ran ok but not as good as I wanted. I bought a popup piston for it and then the other day i tore it down. This sealant was 100% cured and not a drop of air in or gas out. It took some time to get all of the old sealant off but I prefer that to not sealed.

Worked well to seal aluminum crank case halves together on an old 1970’s 2 stroke snowmobile motor (Kohler K340-2FA in a 1978 John Deere Spitfire). I also used it on the crank seal edges to make sure they were air tight.

Great product that I have been using for years. Extremly slow shipping from seller. Is this stuff on a slow boat from China?

This was the first time I've used Three Bond specifically, but it's the same as the Yamabond that I've used previously. I used a light coat to seal the case halves together on my son's dirt bike. Rubber gloves are recommended when smoothing it out! It sealed up no problem. No leaks!

It is a great product

Cleaned up crack on aluminum oil pan after draining oil. Applied thin, multiple layers of Three Bond, let sit for 24 hours. Added oil back to car, have been daily driving for several days with 0 leaks. Will update several months from now. Update: 3/8/23 Still has original application of three bond. Has been through all the seasons, even a bad winter. Somehow or another, this stuff stays on, even exposed. Well worth it, saved me hundreds in repair costs.
