If the shiny is mica it should be ok.
Does it flake off? If so it's mica..Sometimes binding layes with mica desolve easy. If it's been out under a tree has fertilizer or bug spray gotten on it? Test it in a bucket of water for a while (a month since your not using it right now) would make a nice addition.
