My assumption is that the edge control doesn't mesh well with the glue. There's some sort of oily protectant that hates the glue and that's why she gave up on me underneath my bonnet overnight. I don't know. I try to be fair and say user error but once I get some spray, I'll update the review.
Edit: It was still pretty sticky but at least this time it held okay..ish? The got2b did more than the glue in this kit, so.
The tools worked well, I can say that confidently. The strap things for the edges, all that. Everything that wasnt a formula performed well.
