I use KBS on my crankbaits and really like it. Easy to apply, doesnt smell too strong, seems to be tough enough for what I'm using it for - I havent had any issues with cracking. When I got the jug it wasnt difficult to open at all really, I didnt destroy the lid. I did put it in two jars with screw on lids with plastic wrap between the lid and the jar. I replace the plastic wrap each time I open the jar to use some. I bought it straight from KBS and also picked up a jar of their thinner for if/when it starts to get thick. I have been using it for about 3 months with no issues whatsoever.
