With a quality rubber coated, aluminum core this gasket simply blows away the level of all other existing gaskets sold. The company is very mild in their claims about their gaskets, they do not claim that they are reusable but as a user I can tell you they are! With reasonable care you should be able to use these at least 5 times. There are a few other things about Lube Locker gaskets nobody ever mentions. First off you never have to use RTV again, which in my case means you don't ruin another pair of pants by wiping the RTV excess on them. Secondly, you do not have to clean off the material from both the gasket or differential ever again because these don't need it in the first place. Thats going to save you at least an hour which has got to be worth the $20 that these cost!
The Lube Locker company has been around for 8-10 years but I remember that they were voted the single best new product when they initially came out and that was by the members of SEMA, a very particular group. All I can really say is that I think these are the only choice when you choose to either use any gasket or RTV. No Employees, Racers, or anyone we have ever sold one of these to has ever come back and said they were going back to RTV... Lube Locker all the way for me!
