Ahh just noticed the rear glass. THAT is what you want, something that looks stock to the average eye. Awesome job.We always use primer in deep recessed areas. We had to custom finish this by marking a line using knifeless tape on the roof and then releasing that tape to get a nice finish on the edges of the material. The added touch to this was to put the 3M Scotchprint 1080 brushed metal on the rear window to keep the continuity of the roof wrap flowing into the back window.
