Stick with CS Seal Coat. KBS is a royal pain in the *&^% !
I have been really happy with the crankbaits (and jigs) I have used CS Seal Coat on.
The expensive jar of KBS cured between uses (I thought I sealed it correctly!).
I buy the big jar of Seal Coat so I can dip and drip and after I seal the lid back on I put a plastic bag over it with a big rubber band. Still using it 9 months later!
