Instead of using spray adhesive for applying the paper patterns for the stations, I found that thinning wood glue with water and rolling the glue out with a foam roller, then apply the pattern,The result is great, I always have had problems with the paper curling off, using the spray contact cement, plus the wood glue smells better.
Today I found mixing pots at a PPG auto body supply store,they have every mixing ratio you could think of on them,8oz cup $.30, quart size $.35
Disposable gloves,If you have a Interstate Batteries supplier they now sell blue nitrle gloves that are textured for grip, being nitrle, the epoxy can be wiped off to a paper towel, I dont know the price, the brand is Gloveworks.
