I haven't made any progress on my foam core inglenook. But I did have some foam core left over. 3 pieces 20x40. I recently got my new air compressor fired up and since my spraybooth was lost in a the move several years ago I needed something. I am spraying acrylics exclusively (or at least plan to) but wanted somewhere to spray into that was a little better than a cardboard box. What's better than cardboard? FOAMCORE!

Need some help! I am starting, for the very first time in my career, to build a wood kit that I've had for nearly 30 years. It's a caboose and the instructions say to glue sides together and then use Scalecoat Sanding Sealer. Since Scalecoat is no longer in business, what is an alternative, keeping in mind I am not building a fleet nor am I sealing the wood floors in my house so pints, quarts and gallons are not acceptable?
