We're looking at doing a full wrap on a cargo trailer. I'm not sure what brand but picture your typical Carmate or Haulmark trailer with screwed on, overlapping aluminum siding. Question #1....is it standard procedure to cut the vinyl at the point where one aluminum panel overlaps the previous one or is it better to heat the vinyl and conform it to the step? Second question....I know there are differing opinions on the "remove and the reinstall screws" vs "wrap over the screws" method. Which do you prefer and why? And if you wrap over the screws are they just treated like a bunch of small rivets? Can you do screws with or Rollepro or is there a better way? Thanks for any guidance you can offer.
