Finally got some coroplast yesterday. I have made smooth wheel covers with it so far. I'll probably do rear skirts and replace the cardboard grille block with a coroplast one next weekend. If I have enough left over, I would like to do a partial belly pan that will cover from behind the back tire to the rear bumper on the driver's side. There is a big empty space there, which on the other side is mostly taken up by the muffler.
My friends all think I'm a dork.
