I finally finished with my quarter window decal project. It's been in the works for a couple months. Decided to bite the bullet and finish the job. I started with 20X14 decals from elevated_auto_styling on eBay. Made a stencil of the window. I only had to make one (just flipped the stencil for opposite side), traced the stencil & cut it out. Then applied & did some fine trimming. Also note the window latch location didn't interfere with the stripes, so that was a plus. The application was probably the hardest part, for me anyway.
I know it's not for everybody, the purists are probably shaking their heads and rolling their eyes right about now... but I like it.
