Completely frustrated with applying long panels on RV (Please Help!)

[CSOCSO]

A few times I've had to wrap box trucks in 85-90 degree heat. To keep the panels from stretching, I put a 10" (approx) wide strip of application tape down each long edge. A little extra cost and time, but my panels would have started out fine in the morning, at 70 degrees, and been longer and out of alignment in the heat of the afternoon. I do peel the backer about 18 inches at a time, and start in the middle of each panel, but there are lots of ways to do it.

I do this if i have to install cast material outside or if the print was too fresh and the edges of the vinyl would start curling on me.

Here is another option I have never seen before, they some how tape all the panels together first then apply to the side of an RV as one large panel.

They also tape a temporary meta strip on the side of the RV to allow them to hold the graphics in place using magnets.

Has anyone on here tapped their panels together first like this and apply in one large panel?

very interesting, I did not know this variant! This reminds me of my installation, almost 2000 sqm
