I'm looking to make a boat tail for my ford focus. I want to make a permanent boat tail and was looking for ideas because I have no idea how to tackle the tough angles and curves on the focus.
Coroplast is cheap and seems easy, but it's hard to make curves in and I'm not sure how I would support it. I was thinking fiberglass on foam, but I'm not sure how I would go about putting that together.
I've attached 2 pictures of what I'm dealing with.
Any Ideas?
