I use E-tex lite on my musky lures and KBS on my 6" and under. One must give any top coat time to cure if in a high humidity area then it takes longer even when mixing the humidity is getting into the resin, I found to use as much plastic for mixing, in other words don't use a paper cup it holds water not much but its there. Plastic stiring sticks are better, you can make them out of clothes hangers and use them over and over. Seems to be a little picky yes, I even have a hot box for curing in the summer and not needed in the Oct. thru April months when humidity is low best time for airbrushing. I think I tried them all and have settled on these two.
