I remember asking this a while ago, but I just used the plasti-dip and It was perfect. I never did figure out how that would have worked, and everyone around here started talking about "their opinions of what would happen" or how they think its some kind of conspiracy, and then argued about it either being the miracle material, or an overpriced can of crap.
I just let the thread die, now I cant find that other guy's thread, and I cant find flex seal anywhere.
