"Military grade aluminum"??
Methinks that is probably similar to the "Fine Corinthian leather" that used to be advertised.
That is to say, it is an advertising gimmick that does not really exist.
Then there is the famous "Aircraft grade" aluminum. Do they really expect us to believe that the item is made of FAA-PMA certified aluminum? That FAA certification is the only thing that defines aluminum as "aircraft grade". It is the same alloy that is used in other applications.
Yes, I do know a little about aluminum. During my working career I worked in an aluminum smelter, I worked in aircraft manufacturing using various aluminum alloys from 1100 aluminum to 7075-T6-511, and I held an A&P license, doing mostly airframe work.
When aluminum gets stretched and work hardened, it is very difficult to push back into shape, weld the damage, and grind it smooth so it can be refinished. Cutting out the damage and patching it would be much better and easier. Again, welding and grinding would be required (I don't think anybody would want a riveted doubler and patch in their vehicle, as an aircraft would be repaired).
It just might be better to replace the entire assembly, and scrap the damaged part.
I think I'll just keep my old Dodge...
