Thanks for the suggestion, and you also suggest lamination right? I have the rivet brush
I have to side with others. I've been installing for a year +, not much on vehicles.. but boxes with 20-30 rivets each. I still mess up and the rivets don't look perfect. Luckly it doesn't matter and we can just let it be. I had to be shown how to do it, all the videos online teach you nothing.
I've tried a rivet brush... I've tried the rivet roller... And while they do help, you need to learn how to properly lay down the vinyl over the rivets. That's something they don't tell you... You don't just apply it like normal, then brush it and it'll magically work. You need to set it up, then the tools make it easier for you.
I'm not saying don't try it. I just suggest grabbing some scrap material, and trying it out before taking a box truck with hundreds of rivets. Goto any utility box, most will have rivets.. Just practice on one for a bit, see if you're comfortable with it.
And to answer your question.. We use 180 with 8518. I've heard good things about Averys air release, but haven't been able to try it. Generally you want something with air release / egress, conformable, and with a controltac type glue.
And if your printing... yes, you have to laminate. If you're using solid colors, you don't need to laminate.
