Gosh, Mike good to hear from you .....
The K&B was a two part mix .... the KBS is a one part urethane ..... it cures pretty good .... but I guess I haven't thinned it enough yet to feel comfortable using it .... I'll try some test pieces. The K&B clear using satin finish hardner was thinned and used to brush down 0.5 oz glass onto the raw wood ..... a second thinned coat with the satin finish hardner and sanded was a pretty good base finish.
I'll always remember the '92 Nats in Chicopee when it rained ... it rained a bunch .... Mike patrolled around the stunt circles with swim mask, snorkel, and flippers. Great times.
...... good to hear from you ...
