Stainless steel petrol tanks

Had a lengthy conversation with Ben at Rayspeed the other day, one of the topics we covered was running without an air filter and possible accelerated wear of cylinder plating, Ben was saying he'd not seen any appreciable difference in wear running without BUT he was saying the biggest plating killer is the use of stainless long range tanks and the problem was all the internal crap left after welding manufacture and abrasive from the polishing process and the fact that over the years they have seen and rebuilt numerous engines damaged in this way.
Anyone on here experienced similar problems?
Surely it can't be to far from the realms of reality for tank manufacturers to ensure the thing is clean before going on sale?
