Hey Eloy
I'd like it to look similar to the front grilles>>Rather than 1" X 1/2" thick I'd prefer 3/4 X 1/4 to maybe 3/8' thick. PVC since you can shape it with a heat gun & can plasticweld if need be. But so far all I've found is 1/4" It will be flush with the body. Also adding a panel underneath to direct air under the bumper rather than into it. So if you know anyone, do tell.
