[Christ]

Looks good, might want to attach some "L" braces to a few places though, so it's flatter, and not turned out on the sides.

If you're having problems with it being/getting kinked, you can always put a few thin wires long-ways across it, with tape, and heat-form it, when you go to make the permanent one.

You make wires that are formed to your bumper, then slowly work the plastic onto them with adhesive, while heating it up so that it's uber-flexible (think: close to melting), then tape it as it cools, then work another 3-4inches down. It will form to those wires, which are already close to the shape of your bumper, which makes it so it won't kink with a little extra bending.

I tell people to pre-form it a bit when using it in their gardens as well, so it won't leave gaps between stones and itself when it tries to straighten out. (it's lawn edging.)
