The pipes you saw on E-bay are mine and yes they are sandblasted. The old pipes usually look very discolored and as you all know I like nice shiny pieces. The pipes can be clear coated and that will make them last longer or if left they will eventually start to oxidize again. A silicone spray does hold them but I doubt anyone will want to do that to often. I do much of my own sandblasting but these were done in a bulk batch. They really look nice and as you noted are on sale on e-bay at this point. I only have the one set for sale so when they are gone they are gone. This was written to answer all the e-mails I got on it asking if I was the one that did the sandblasting. Ken [Non-text portions of this message have been removed]
