....personally I like screws with the square heads[SS] and the VHB tape on 2 sides.....It cost me +$300 to have my trailer done that way.....but it is more than weather resistant and the polyisocynate foam did not penetrate and expand in the seam......I do have some ripple on the sides to deal with but that is flex from loading and unloading vehicles and sun of course and some sidways pressure form the foam.....plastic rounds are 5/8 inch plastic rods that keep the VHB tape form setting while you move the sheet around....I have used a table along the side to keep the sheet level and have something to step up on.....geofkaye
