I'm in the process of gathering up supplies for my upcomming restoration and wanted some opnions. We all know the joys of the Blazer tailgate, when water gets in the bottom of the doors/tailgate and rust forms. I'm thinking about lining the insides of them with 3M Rust Fighter I and if there is any rust already, Corroless. 3M says it designed to replace the factory corrision "proctection" (I think they were asleep at the wheel on the K5s, lol . It would nice to not have to worry about the tailgate/doors rusting from with in. I've got such a huge tab going but the K5 is more than worth June 2001 - The Texas Sawz All masacre begins. Be afraid rust, be very afraid.
