*by B***S on 28 October 2024*

Although I did not use this as a covering, I did use it to glue 32 ga steel to a structure with both a positive and negative curve. Held in place with a sandbag, it seems to have worked quite well. Of course it’s always difficult to give initial quality on something when that quality will only become apparent after at least a year.
