Back in '95...
I rejected two of the aluminum tube spars. Had Skystar send me two new tubes. They did. The new spars still had some marks but were acceptable. I still have the old ones. I think the problem lies in the manufacturing process and shipment to Skystar (Kitfox). I don't think that there is care and concern from the tubing manufacturer when they are stacked, boxed and shipped to Kitfox. My personal opinion is that they left Skystar that way. I received them wrapped in foam.
