I was curious if anyone used a varnish spray or anything of the like on their plaster?

All thats really available to me is Plaster of Paris, and over time the things I make will accumulate small chips. Would anyone know of a varnish spray or something that you can get from an arts store to spray before or after painting my plaster projects to give it some extra longevity?

Some folks have had success with a coat of Future Floor Wax.  Some coat before they paint, some after they paint, and some?  yup, you guess it!  do both!  I have had the most success with a couple of coats of Krylon Satin Clear Finish followed by a coat or two of Testor's Dullcote to knock down the shine.

My suggestion is to experiment a bit and see what work's for you.

Alternately (and far more expensively) - you could use a super thin Cyanoacrylate (super glue) and give the build a coat of that.  It'll soak into the plaster and give it some surface strength.   If you choose to try that route - don't buy the little bottles at your local DIY store - go to a hobby store (or online) and get the stuff in bulk.  Largest bottle I've gotten is 8 oz - but I seem to recall larger.  It's usually used for model R/C cars.
