For reference, the krinkle gum is the thickest at almost 1/4". I use Krinkle Black for my rain shoes and they're quite grippy, even when the texture wore off. It's also thicker than the Rain Dot. The Urethane is actually semi-opaque, which would look cool I think.

And here's some descriptions. Note the prices are probably out of date (maybe not), but will give you a ballpark figure.
