Josh -- What's the big difference between 3951RA & 3751RA? We used to use 3751 for cab doors, etc. when we first got our printer, then used 3951RA for doing wraps and 3551RA for cabs, then switched to 3M IJ180Cv3/IJ40C-10.
How does it handle the indents on vans around the wheel wells and where
windows would be?
3951 is the highest performance vinyl they have. Yes, it's more tacky.. Why? It stays where you put it. Takes a bit longer then 3751 to install, but stays on and conforms extremely well.
3751 is really really easy to apply. Low tack, better than 3M for clarity with much more shrink ability. Ultra bright white point so your graphics really pop.
Honestly, you can use 3751 on all your wraps. I use it on the deep sprinter channels with no problems. Camaros, dualies, HHRs. All 3751 good.
3551 is best for flat only in my experience. Trailers and box vans.. For the cost though.. 3751 and 290 can't be beat.
Tell your vendor you want the 3751RA combo pack.
