Possibly, but I rather think that the pitting in the old chrome did the real damage, allowing the corrosive bath to get through to the rim metal. There's not much thickness in a drum rim in places, so it didn't take much to render them useless. Lesson learned, though. Luckily, I'm not such a purist as to insist on all-original parts, as I'd never be able to obtain genuine, new-old-stock Camco rims. I've used Tama rims instead; Tama bought the Camco hardware anyway when they were split up (the shells went to DW, along with the round-cylinder lugs...), so...
