You folks got me to thinking about storage. I went to a walk in closet in the spare bedroom that is rarely open. I knew there was powder coat of various ages and there I found a box with this awful bright blue from yesteryear. Prolly the 80s. So I checked it and a few other paints in there and they are just fine with no extra care at all. They have just been kept dry. Even up north here it can get pretty humid but they don't seem any worse off than new. Sometimes I just over think things and should just focus on the fun parts. The rest will work it's self out:cheers2
