Working on various old trucks now, I've noticed there can be a big difference between what type of metal trim is used outside a vehicle as well as inside.
So, how can one tell the difference between aluminum and stainless parts? I'm no metalurgist by far, and I have seen some pieces off my '72s that I couldn't decide what they were made of?
Dull stainless can look like aluminum to me. Polished aluminum looks far different than dull. How do you tell whether or not a piece is just chromed pot metal or not if it's 60 years old without pitting and it's non magnetic?
There are various clues that are pretty easy to see, but I've ran into some odd ones with one person telling me it's aluminum and another stainless. Obviously corrosion damage, pitting, staining and patinas are indicators depending on the how and whats involved.
What about the stuff your not sure of?
Thanks, Jeff
