I have a large stash of Champ decals from the 80's and early 90's. Can they just be used as is or do they need to be sprayed or treated first because of their age?.

Best to check their condition prior to use by using a bit of the page that you have no real need for; snip off that bit and see it retains integrity in water; if not, spray that set.
However, the last set I used, 1 of the 2 pages worked perfectly, while the other completely fragmented.
So, when in doubt --> overspray!
