Nicely done man, you've got skills! Almost reminds me of the Challenger's spoiler, I love the lip styled spoilers on Chargers. My only critique would be making more of a gradual angle on the side that faces toward the front of the car, it looks too vertical.
actually I made it all one piece. I also made a mold from it after I made the part that I am going to put on my car I found some low spots in it I am sanding on the mold today to try and get it perfect I make them out of fiberglass the only color will be black gel-coat I do plan on selling them when I get it to where its near perfect
Cool. Sounds like a lot of work. Of course I'm no stranger to custom work either, so I know it's not about the hours, but rather the end result. Looking forward to seeing what you come up with over time, because I'm sure you're not stopping there.
