OEM Quality
Ive always used regular gasket maker. I was rebuilding a Subaru 5 MT and decided to this time use what was called for from the factory. Gasket maker is gasket maker, but this seems to work really well and firm up quickly. It was easy to use as with any other gasket maker. I sealed the transmission and didnt experience any leaks. Its a quality product. Its slighly more expensive than other brands, but worth the cost. I noticed its lasted longer than other brands. With others you use it once and its hardened by the time you are ready to use again. This stuff is still liquid in the tube months later.

OEM Quality, legit seller.
Worked like a charm, this stuff has a 1 year shelf life but came only a few weeks since manufacture. Very nice.

A must have if your rebuilding UTV engines!!
This is awesome oem quality required for assembly of Yamaha crankcases and other brands where it’s metal to metal or sealing rubber gaskets to aluminum cases or valve covers on motorcycles, skimobiles, UTV, ATV…etc!!

Replaced genuine Subaru block sealant
This product works perfectly for Subaru engine case halves. Thin and does not skin over quickly allowing time to assemble engine parts.

El pegamento es excelente para motores pero no para transmisión
