I have a 1969 trailer home 20x50 FT SQ. Aluminum siding and I want to face-lift with Vinyl. I don't want to remove the aluminum. Will I have warping from heat or mold or is it a bad Idea all together. I really want to do this. Will thin insulation Help?Anyone with experience in this let me know. Im in Seattle WA where it is a short hot season, mostly 80 degrees... Thank You!! PS: The Aluminum is very flat and would be easy to cover.
