I keep seeing "do not use the white foam". Since I happen to have a bunch of it from other projects, it sure would save me money. Besides, both Home Depot and Lowes here don't seem to have any "blue" or "pink" board in stock. I have been seriously advised to NOT use florist foam because it disintegrates into an engine clogging dust.
Also, is it OK to do a 3/4" layer over my whole layout (HO scale)? It is approx 110 sq ft in a "C" shape (bent dogbone?) There are many places on my layout that it simply NOT feasible to drill through to run wires. I could just slit the foam board to lay the wires and cover w/ turf. The vast majority of my attempted layout is salvaged stuff from a friends O scale layout he discarded to build a new huge one in his 2 car garage. The last layout I built was a simple S scale oval when I was 10 yrs old, and that was 50 yrs ago .. LOL
