    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

Copper Spray-A-Gasket? Hi-Temp Sealant

Has anyone used this or similar on a head or base gasket?
Was thinking of trying it,but think by the time I get cyl block in place it will already have dried.

Does that matter anyone know?

Thanks
 
I've used it on my turbo trucks, it works quite well for holding boost with stock gaskets. Just use it like five minutes before you put the head on.
 
It remains tacky for quite a long time. It will get on your fingers and everything you touch afterwards, but don't worry about a need to rush, take your time and do it right.
 
It's a great product, but completely unnecessary for assembling a G S motor .

Assemble everything dry, maybe some grease on the valve cover gasket
 
I used hi-build aluminium spray paint on the base gasket of the 850 three summers back.
It was only after I had cleaned off the old gasket that I saw the gouge marks some of which were .020" deep.
As a precaution I applied the paint to both sides of the gasket. So far so good, dry as a bone.
