Just got back from picking up my Coroplast!!! I'm excited 'cause I only paid $9.25 for each 4x8 sheet. The real kicker is that the vinyl supply company I purchased it from has multiple colors available. White, Off-White, Green, Yellow, etc. I got it in black so I wouldn't have to deal with painting it. Yeah, no overspray...not that it would matter, the paint on my car is pretty much 'dead' anyway. Going to check the weather for tommorow (day off), maybe get it done.
***What kind of hardware/screws did everyone use for installation? Just self tappers or did you drill holes?***
Self tappiung screws with predrilled holes when screwing into plastic or steel. Use washers to keep the head from pulling through. For coroplast to coroplast I used coarse thread drywall screws. They hold the coroplast well. After a week my coroplast is secure. Nothing has losened up.
Just completed cutting and fitting my rear tray. Thought I would start in back where the panel is smaller so I get used to working with the coroplast. Am planning on tucking the panel up above my rear bumper lip (nice and clean), but I need to get some different hardware 1st.
My question for anyone/everyone is...would it benefit the aerodynamics of the vehicle if I attached it under the rear bumper cover and let some stick out the back? I'm not worried about the looks of the vehicle, so if it had a 3" lip of coroplast sticking out the back would this direct the airflow more efficiently? Lower the drag? Thoughts?...
