Installing the side sheeting on our trailer. It is flat sheeting (no brakes) and is tending to puff outwards. Anyone have tips on getting the skin flat and tight. Here it is mocked up. Thanks for any help

Love your support blocks for the metal!
Smooth sheet metal is very difficult to mount and keep it absolutely smooth. Older Kits are well known for ripples here and there.
One solution is tasteful screws into the wall. Of course, they will be short because of the ply wall. Our Corvette came with siding screws. I would go ahead and install the skin and see how it looks with the windows and door in place.
There also might be places that a light would anchor the skin.
Keep us in the loop.

Screws are a great idea. Just a few screws should do the trick if needed.
Any tips on getting the sheeting attached? So far I was planning to start in the middle and working my way out. Is this the typical way to to approach this? Any videos on attaching sides?
Thanks

Attaching skin is not the same in trailers. Some skins attach the bottom first, others from the top down. Skins with Pittsburg seams always start at the top. The bottom lip is stapled and the next sheet is slid up into the seam groove, then stapled lower down.
I'm assuming yours starts at the bottom and goes up from the photos. I usually start at one end after clamping and viewing the skin. Don't think the starting point is necessarily important, but the skin fit is. In other words, be sure the fit insures no leaks before final attachment; tight to the next seam at the back, middle and front.
Mobiltec has videos.

The upper sheet just lays over the top of the lower sheeting and is fastened with #6 sheet metal screws (orginally twist nails)
The temperatures are in the 50s today. Should I warm the sheeting with a heat gun to get it to expand closers to where it would be on a hot day? Probably over thinking it but want to do the best job possible.
Thanks for the help.

I'm a little late but warming is always helpful in chilly weather. Also, use thin butyl (sold as Tacky Tape by Schnee Morehead in roofing stores) at the seam. I use 1/16 x 1/2 inch for skin seams.
The roofing Co sold me some caulk used for metal roofing for my 66 Kit. I used it behind the butyl on vertical seams, but really wasn't impressed with it. It is Goop, after all. Extra insurance, maybe, and invisible. Can't hurt. From the factory, the Kit came with some sort of caulk at the skin seams, but no butyl. It leaked there.
If you're going to pre-drill, do it before the butyl is installed. I seem to get a better screw seal with intact putty. If you forget, a sharp tap with a nail set will start the hole pretty well and do less damage to the butyl than a drill bit.

Do you think I should warm the sheet with a heat gun before stapling it? Or I could heat it with the buffer? Seeing how much slack is created by the heat when I polish it I am concerned that my side will look terrible on warm days if I don't heat them before tacking them in place.
Thanks for the input.

Aluminum doesn't really like high speed anything. I'd use a heat gun. I think it was Soup who mentioned blasting aluminum could warp it beyond repair... not saying buffing would do that, but it may get hotter than wanted. A little more control with the gun.
I guess time will tell with your skin. I'm certainly no expert with flat panels. I would think older aluminum is tougher/less likely to warp than on a newer trailer.

Steve Loomis tells me it's better to attach metal when it's hot... Or in the sun... Or both.
It expands when it's hot and shrinks when it cools. I had a little buckle in the front of the Kenny when I first mounted the skin and did it on a hot day. When it cooled off it went away. Never came back LOL. I'd rather be lucky than good any day.

Nope, that's window stuff and WAY TOO STICKY. Trust me... When installing glass you have to spray with Windex before laying the glass to allow adjustments. tacky-tape.com/ Tacky Tape is basically butyl, 1/16 x 1/2. You'll have better luck buying from a local roofing company that does metal roofing.
