Yeah,Glass!
When you are using resin or just cutting something for a long or circular part, or just using a blade to remove parts from the Sprue. Put Glass on your work surface. Why? Well, Tempered Glass is a great Flat cutting surface. I mentioned Tempered Glass. You remember those Stereo stacks with the Glass doors? That's where mine came from. Thirty years later and it is still scar free, and allowing perfectly square cuts and with the right tools perfectly square builds. They even come on IKEA and SAUDER Brand(WAL-MART) as well as other types of Do-It-Yourself Cabinets! both double and single door.
It can be Tinted or not, That part doesn't matter. Some had holes for the hinges and a lot just clamped it between a nylon or such gasket. The great part is when you are working on a kit, you are on page twelve, maybe. Where's your instructions? taking up room on the bench that you need to do these steps. So, Put you instructions Under the Glass. This gives you Freedom to work, on top and keeps the Instructions from getting, paint, Glue, or Decal water and Setting solution on them. Plus you don't accidently cut a slot in them.
If you can't find one of those then invest in a Glass Cutting Board you can find at Kitchen and Culinary stores. The investment is worth it. Right, if you get it from the Culinary store, it will be costly. So look for the stereo stacks at yard sales. You will get a nice Topper and if the cabinet is in fair shape, a place to store your compressor and paints after adding some impromptu shelves.
The other reason for glass is Resin. This stuff before mixing in the hardener is Sticky and Yuck! So, if you are working on glass, when you are finished just wipe down the whole thing with Lacquer thinner and Viola' you are all clean and pristine again. Plus, if you need to have an absolute Flat bottom to something, like the Glue Bottle Holder I mentioned in another post, Just take some release agent, rub it on the glass out of your way, Then place the pipe or bottle ring down, Insert the pattern and pour. You will then get a Perfectly flat bottom that pops off easily when set. Make sure to use the release agent though.
