I use a spray lacquer sold in art stores for protecting water colors (and seems
to be the same as the sprays for photographs sold in photo stores; at least the
ingredients are the same). Krylon is one brand, but there are others. Better
than mixing your own and brushing it on. I'd keep away from anything with wood
alcohol (methyl alcohol), and amyl acetate can affect any plastic materials
that the fumes might reach. (Incidently, amyl acetate's common name is "banana
oil" and it is used in imitation banana flavors. It is a plasticizer, and can
affect many plastics.)
