Body Mounting Bolts

["John Zimmerman" <JohnZimmerman@vandorndemag.com>]

When I removed the body on the 6, I seem to remember a putty like substance on 
the threads of the bolts and under the washers on the floor pans.  I assume 
this was to keep any water from coming up through the mounting holes in the 
floor.  Is this the same stuff used to hold the spacers in place when lowering 
the body back  down.  Is this a 3M product?  Any input would be  greatly 
appreciated before I put it back down.  There is a light at the end of the 
tunnel!

Thanks,
