Solid color vs. printed fleet graphics
A solid color change uses cast color-change vinyl (3M 2080, Avery SW900). Fleet branding uses a printable cast film plus an over-laminate for UV and abrasion protection. Printed wraps need extra footage for bleed and registration, so quote 10-20% more film than a plain color change.
How much film a van wrap needs
A mid-roof cargo van runs 75-130 linear feet of 60-inch film (roughly 300-500 sq ft) depending on wheelbase and roof height. High-roof Sprinters and extended bodies sit at the top of that range - measure the actual panel height, since tall sides exceed the 60-inch film width and require horizontal seams.
Rivets, seams and corrugations
Riveted and corrugated van panels are the classic failure point. Lay the film loose, tack the flat field, then use a rivet brush or pin-and-heat technique to conform film into each rivet before it can tent and lift. Post-heat to 90-110°C to set the memory.
