KBS Bob Posted November 2, 2020 Report Share Posted November 2, 2020 I am repairing rust on my tailgate for my 2013 GMC pickup with KBS products. I purchased the 3 part kit ( KBS KLEAN, RUST BLAST, & RUSTSEAL). After completing steps 1 & 2, I have some flash rust on the surface. Is there going to be a problem applying the RUSTSEAL to the surface with this much Flash Rust? Quote Link to comment Share on other sites More sharing options...
