ali is best used in the straight flat panel areas - grp on things like nose cone etc - ali is way way lighter - found that out on one of my cars when i chopped the boot box in half and replaced it with ali. wow real weight saving just by picking it up i could feel it.
ali can look really cool as a bare sheet it still is practical - although if going out in salty conditions or wet it needs rinsing and drying thoroughly. or just paint it, etch it, clear coat it, mask it and paint it with patterns.. the options are good with ally. expensive to buy tho - use 1.2mm for bodywork. bends easy 2mm for stuff that needs strength - thats a lot harder to bend.
