Hmmmm...I am interested in this response too since I just put my Manual transmission back together using Hylomar on the mating surface of the two transmission case halves. I also used it in conjunction with the paper seals for the Bell housing and end cover (where the shifting is). I didn't install the transmission yet and it's sitting on my work bench so if there is a problem I won't curse to much since it's not in the car yet ;). I think the Hylomar is only good on Machined smooth gasketless surfaces (such as the manual transmissing casing halves are). As for anywhere else that has a gasket, I would not use Hylomar alone (even though it says you can). I know if you put to much of it on then you can cause a problem where it will keep the mating surfaces to far apart from each other and cause small gaps. You have to use THE LEAST amount of this stuff. Steve -- In dmcnews@xxxx, jtrealty@xxxx wrote: > I would like to hear from anyone with experiance using Hylomar.
