I have used both KBS clear and matte on plastic crankbaits, pretty happy with results. I use 6 or 7 coats and try to spray coats 10 or 15 minutes apart, then let them dry for a few days. I spray light coats. I have had a couple of lures crinkle, I think it was because I added a coat after they had dried a couple of days, but not sure. It will fog up if sprayed outside when humid, I spray it inside in a booth I built using an inline 6 inch fan running into an activated charcoal filter used for indoor grow tents. It works really well. I've fished with lures I cleared with KBS all summer and haven't noticed any yellowing or peeling. These are jerkbaits I cleared with KBS, the best thing about it is how easy it is to apply, time will tell how durable it is.
