Default DIY aggressive rear diffuser...under 100 bucks!!!

I was gonna make my custom diffuser a long time ago, never had time. Finally I found some spare time last week. I was working on it for about 5 days, 5-6 hours after work, put about 30 hrs into making it and using basic tools and materials that can be found at any Walmart such as:
- plastic board (1/4" x 48" x 72") $20
- 1gallon of fiberglass resin - $40
- set of brushes - $10
- 2 cans of truck bedliner - $15
- hardware - $5
- brewskis

I used 3 5/16 long bolts to mount my diffuser to the spare wheel compartment and 6 screws to attach it to the rear bumper.
The diffuser is very sturdy and fits like a glove.
All under 100 bucks.
I might be making another one, with differently shaped fins....not sure.
Anyways, enjoy the pictures!
