    I have a couple logos printed to Orajet 3551, lammed with 290. I need to place them on the back end of a propane truck. They measure rougly 18x24 inches each; I'm concerned about the compund curve of the back end, unlike the sides...Any words of widsom out there??

    Start in the very middle if possible and work your way out in a circular pattern. Dont put transfer tape on it, take off as much of the backing as you can, go slow, and use a felt covered squeegee. A second set of hands to hold the opposite side your working on helps too. You'll need a heatgun or propane torch (hopefully no leaks on the truck so you don't go boom). You can also use some 3M Primer 94 on where the edges will be (just mark where it will be with a grease pencil. Apply 2-3" wide strip overlaping around perimeter and let sit 15min before putting on decal. Wipe off excess afterwards with Isopropyl alcohol), to keep from lifting. You will undoubtedly have some stretching towards the corners, so having no outline/border helps too since you can then trim it straight afterwards. You'll also need to post heat the vinyl so that it learns the shape of the tank.

    Couple things ive done in the past is make my print 1in bigger and then trim it off square after putting it on (this takes some of the tension off the edge so it doesn't curl) and the other is try doing it with a scrap piece first (just don't push hard and no primer 94) to get a feel of how the vinyl will conform.

    Whatever you do, do NOT use Primer 94 with Orajet vinyl. This has been discussed numerous times here on this forum and here is a link to an article discussing just that...

    Orajet films have aggressive enough adhesive that I doubt you'll have any issues anyway. Working out the wrinkles as you work your way out to the edges will be the worst thing you'll have to deal with.

    Pics people!!! It helps so much better to see what you are doing!

    Different techniques for different applications!


    At 18x24 that is small but what are you are putting it on matters

    Might be a little late, but our seller just recommends the 3551 for signage/flat stuff. Should be alright for this application but I’d keep an eye out. (Pics would help)
