thats cool, I have been in several larp events in my aluminum platemail. Its super shiny wont rust, and its light.
dunno if your going to paint it or not, but I went with 1/8 inch aluminum and shaped/welded it on a workbench and english wheel. It didnt turn out to bad, and it was pretty easy to work with. are mages allowed to wear plated armor in Larp?
