i find it hilarious..... your in colorado, and i am in florida(its a lot hotter here)..and your tellin me how much shrinkage shine rite does???? YOU ARE WAY WRONG!!!!!
i have been using shine rite since it was offered and i was using its ORIGINAL NAME BRAND (which was GMI CALENDERED VINYL) and i have jobs with GMI on it still out there. the guy i did this truck for...........has a dead truck at their shop which i lettered in 1998, YES 1998!!!!!
IT WAS LETTERED WITH GMI CALENDERED ....... he told me, that truck, the lettering is still good....... but some cracks it it))))))))))))))))
in my experience(since 1992 with vinyl) the only CRAP VINYL I EVER HAD ANY PROBLEMS WITH WAS AVERY!!!!!!!!
BUT..you are right on how i laid the vinyl.........I DIDNT FOLLOW THE BELT LINE...as it is wider near the front door and runs up hill to the back of the van. also the roof line does the same thing.
if you measure the hight on the upper panel on these ford vans, near the front door it is 24", at the back of the van it is 22".
its better to "eyeball" to level then follow truck beltline.
