Well, I'm definitely married to this track plan now. Once I had the risers and inclines mocked up, I traced their outline with a sharpie and then glued them down. On my last layout, I used foam tack glue. This time around I used silicone caulk. Squeezing a tube of glue can be cumbersome and tough on your hands after a while. A caulking gun on the other hand is a lot quicker. I imagination I'll do the same on the road bed and track.
Once the glue had dried over night, I used plaster cloth (Another Woodland Scenics product) to cover the flex gaps in the riser and inclines. It was a messy job that took a good bit of time. But I;m finally ready for track.
