Installed the new notched spoiler today. With the exeption of putting the darn Challenger decal on crooked (glad I bought 2), it turned out great. I love how it's deep water blue from the front and blacked out from the back.
Years ago I plasti-dipped the lip and surround. Now with knifeless cutting string, most are vinyl. The LED lights are smoked which was awesome. It is SO MUCH better, IMO, then the red bar. It came out way better than I was expecting. Cheers!
When applying decals, spray the area with Windex first. Slide decal around to your content, press it and let it dry, occasionally pressing it flat. Remove paper from front whenever it suits you.
