The moldings you have will be a thicker gauge malleable AL alloy. Modern AL bodied cars or exterior components are thin and AL has no memory like steel. Using a hammer and dolly on AL is not recommended unless it is of sufficient gauge and can be heated to anneal it while working it.

Actually the smaller more shaped pieces can be more easily repaired than a large door or hood skin. The way you've straightened out the air cooled deck lid grilles tells me you can do this. There is a lot of YT info on annealing with a carburizing flame using your air/fuel torch.

You can do a lot with wallpaper and window screen rollers. Wood blocks, etc. A metal shop just about needs a wood shop to make bucks, forms and the like.
