take alook at my skirts.....

see post #37 to see the metal bar I installed.
Before embarking on my project, I read both your entire skirt thread, and MetroMPG's, and as a result, I've used a "carpet bar" on both sides as a reinforcement... I should have gotten a pic before I fixed the skirt... For now, I just taped the trailing edge of the skirt firmly to the bumper cover with plastic strapping tape... I have since bought more nylon rivets, so another solution is in development...

I haven't found any PolyMetal or AlumaCorr anywhere near me locally; in fact, I haven't even found full sheets of coroplast yet... Not many sign shops here in WV, given that I don't live near a major metropolitan area... However, on Wednesday, I'll be in Charleston most of the day; maybe I'll drive around and find something...
