When I got my dad's Slingerland kit from his attic, and after a good cleaning to get the nicotine and all that off them, it was pretty much brand new looking. Bear in mind he had the same charcoal colored shingles on his roof that I lugged up the ladder when we built his house. It was roasting in the summer and freezing in the winter up there and I saw no ill effects on the drums. The wrap and seams are all super tight. The only rust was on two cymbal stands that I think were left out in the rain a few times after a drunken jam session on the neighbor's patio.....
Take this for what it is. An example of not having to baby a drum kit to have it last for decades. It was made by rugged Americans to be used by rowdy Americans in a time when everything was made to last!
have a wonderful evening
