By the looks of it the steel tank that blew up in the car had the rubber type coating that can harbour rust between the coating and the Tank. When I do inspections I will not pass a tank with this coating, I think that is the reccomended procedure.
As fo 6351 Aluminums, roaky is correct, a properly inspected tank, one that was properly tested with an eddy current test, is very safe. But from an LDS position I can understand why some wont fiull them, how do they know if this was properly done unless they did it themselves. Sometimes the decal is merely just that, a decal.
I believe the major problems were with Walter Kidde and Luxfer pre 1988. I too would second the thought to put down those tanks, especially the E6498 and SP6498 and anything WK.
To my knowledge there are no legalities about these exemptions but just as a personal preference I highly reccomend putting them away. A tank from 1980 has had a good life.
Besides, who wants to dive with Aluminums anyway!
My 2 Cents.
