JOE RIX: Thanks for the info on the barrel.
Now you really have me pondering which way to go with the zim'!. The PE would sure be a lot easier, but what I don't like is that it looks too "perfect". Maybe I can find a way to add some putty or cut the zim in a few places to make it look more worn. Hmmm... I have a lot of holes to putty and a bunch of weld seams (let alone road wheel work) to add so I'll wait to see your zim' pics before I decide which way to go. Thanks for the info, It's why these GB's are so great!
