I just got a set of 1 5/8 Mac LT "industrial". I called Jeff at MustangWarehouse and he called 3 distributors and I got the last set. They're hard to find, but still available.85GT306 said:Does MAC still offer the chrome industrial plating? I have 1 5/8 long tubes with this and it was a good 3 years before they started to rust. Lately all I hear about is this HTS coating.
