I am about to begin work on a new (second) layout that will be approximately 5 ft X 9 ft using Lionel Fastrack. The layout will be predominately flat with a "recessed" lake and river.
I intend to use QuietBrace over plywood on 1X4 benchwork.
My question is: Should I use insulation foam board over the QuietBrace or use 2 layers of QuietBrace and cut out the lake and river through to the plywood?
What would be the pros and cons of using either method?
Thank you in advance for your comments.
