When I came across this tip about 2 years ago (not my idea unfortunately) I worked a lot with it. Definately very easy to work with. Be sure to use only acrlyics to paint it with! Enamels and oil thinners will melt it, as will super glues. Use only white glue or low temperature hot glue as i have used.
I have stopped using this method now for the main buildings ... prefering to use the cardboard and cork board method ala carlos Elias. Why? Having a perfectly built and painted building ... a wash will always get into seams and melt/distort something. I love the use of washes, and both dont go together very well. I still use the foam trays but now to make molds for pouring plaster, and then scribe this instead.
I believe this method is excellent for smaller details, but only raises more problems when building larger pieces.
Some examples of what can be done with foam trays
If you have any questions ... send me a pm and I hope I can help.
