I ordered from Mame marquees. Yes, it's a big sticker (and of notable quality I might add). It took me and a buddy to install it on a full sized midway cab... went on great, minimal air bubbles. This was on a primed wood surface, unsanded final coat.
Well, it's the end of summer here in Texas, and the humidy (i suppose) has caused the side art sticker adhesive to become worthless and peel off into a ball of destruction. I've used contact cement to hold the salvageable art on one side, which has worked but shows signs gummy adhesive. I'd personally consider getting a can of spray on contact glue next time as opposed to the roll on can of stuff used on countertops. The sticker glue alone failed in the summer Texas heat.
I watched the first video and used it as reference. No mention of glue there.. so that's my warning
