Trim rail on '73 Ambassador coming loose
I am new to Airstream restoration, having recently purchased a 1973 29' Ambassador with center bath (tiny!). The rig is is pretty good shape, but there are a lot of minor repairs needed to bring it up to par.
There is a metal "trim" piece running along across the bottom of the trailer. It cuts across the battery compartment door. The rail has started to come loose. It looks like it was originally affixed with electrostatic spot welds or something of the sort. How can I properly repair it?
