(PSA = Public Service Announcement)
I haven't seen this mentioned (which doesn't mean a whole heck of a lot!) so...
I had some water color paints which had dried in their tubes. Being cheap, I figured I could open the metal tubes, take the paints, and revive them in tiny containers. Knife and side cutters did the trick. But when I peeled away the aluminum tube, I saw dark gray discoloration on the paint – about the same tone as the aluminum of the tube. I guess the aluminum oxidized as some got on the paint.
There wasn't enough discoloration to bother me, but I figured I'd share this just in case...
