Last night the wife and I had a crafting/Star Trek night.  While she worked on some crocheting I pulled a bunch of scrap foam from building the table to work on some ice crystals to use as terrain.  Managed to make a whole bunch of various sizes and was pretty pleased with the result.  I used some cheap acrylic craft paint (only slightly darker than the actual blue of the foam) and dry brushed the edges white.  This morning before work, I took them outside and gave them a spray of gloss varnish to give them a nice shinny look, but to my dismay they started dissolving away despite the paint!  Generally I use a thicker latex paint on foam which will protect it enough that spray paints and varnishes will work, but the acrylic paint is not thick/strong enough.  Probably half are ruined beyond repair, the other half should be alright, but I’ll need to make more.  Next time I’m going to use Future Floor polish through the airbrush instead to avoid further failure.
