Thank you everyone!! I will try all of these. Great idea to test on a mirror!
I was able to store the Clipper in a heated storage unit this year which allowed me to finish restoring it. Just have to install new window gaskets then clean up. Yes, I will take very good care of. Just a fluke that I found in such good condition. Luckily I had been studying Airstreams since I was in high school (a VERY long time ago
!). I knew it was special and I treasure it. These Forums are such a wonderful source. Thank you again.
