Sides coming loose.....

Well, my jerk landlord has asked my wife and me to vacate his property. He wants it back.
So yesterday, I moved my teardrop project to a friend's house. While running down the road in the really hot sun, the aluminum skin expanded and WOW! It got some huge bulges in different places where the aluminum came loose from the plywood underneath. I'm glad I spotted this before I completed the thing.
I'm thinking that I did not get good adhesion originally and I suspect that it's because the wood soaked up the contact glue. So, I think the right thing to do would be to completely remove the aluminum and do it again. I'm just going to get 2 new sheets rather than trying to save the old ones. I'm sure that I'll find a good use for the old ones somewhere.
But this brings up a couple of questions:
First, I think that I should take advantage of this really hot weather we've been having and remount the sides out in the hot sun while the aluminum is at its maximum expansion. That way it will always have a tendency to go smaller than the wood rather than growing bigger. Is this a good idea?
Also, over a period of time during this build, my aluminum has gotten a little scratched here and there and a little beat up. It's not bad but I'm thinking that aluminum can be polished and this "patina" removed. But I'd sure like to know the proper way of going about it. Since I'm planning on removing the sides anyway, now is a good time to practice buffing and polishing with no worries over doing any permanent harm. I can always learn new lessons. lol
