Hi guys-new here. I've had my Sonic for a little over a month, so I'm a little behind on the mods. I decided to try CFing the "shroud" over the rear window and I think it came out fairly well. One thing I did learn-DO NOT follow the maker's instructions regarding placement or using pins to push out air bubbles cuz when the weather changes, those little holes grow! I used lots of soapy warm water on the cleaned/de-waxed surface and the sticky side of the CF, used a plastic squeegee and microfiber towel to remove moisture, surface-mount door guard strips and black pinstripe tape to give it a finished edge. I'd love to hear what you guys think of it. Thanks.
