Sooo... before I name the manufacturer (some may be able to guess if they have seen the same thing) I have had a problem with consistency in color in color change material. I used a dark gray and installed everything the same way, top to bottom, didnt flip the roll. The gray was lighter or darker at some of the seams. Now I used a metallic silver and the same thing. Luckily, I found I could flip some of the panels and the color would match (kinda) but I wasted a good deal of material and had to re-wrap some of the van. I don't feel like I should have to flip panels... I assume (silly me) that the color should be consistent all throughout the roll, from beginning to end.... I changed my mind, it was Avery material. Anyone vouch that this is not an issue with other manufacturers? Ill just throw out my avery swatch book at this point
