I was doing some measuring on my Accord and I would need a 3.75" gap filler all around the tire. The front of it could bubble out slightly and taper towards the rear or the wheel well and would not have to move with the tire to allow for clearance.

I think I would make the top of it attach to the fender and the lower pieces front and rear made out of a heavy plastic that could be shaped and molded with heat to retain the desired shape. The lower pieces would attach to the top piece and to the front bumper and the rear piece to the wheel well.

Any ideas on a heavy plastic material suitable for this.
