Iam really liking the fact that you are doing this thread and in the format that you are. Ihad purchased the Styrospray this past summer to use on a large plane but held off. And now, it is too cold. I did a massive amount of googling one day to track down the product name.

I tried it on some thin blue foam sheet that the electric guys use to cut out their planes. It was amazing how it flowed and filled the foam surface to a smooth finish. It warped the foam. But it is the kind of foam that warps when plane is sitting on the picnic table at the field. It was not a good application. The main thing that I discovered in my test was not to try to smooth it out by continually brushing it. It will get lumpy since it is already starting to set up. The best is to just brush it on with a few strokes and watch it flow out even and smooth on its own.

As an added item, can you start calculating sqare inches when you finish the application and weigh the item?
