WS "Foam Putty" alternatives? - Model Railroader Magazine

 On small seams I use latex caulk, I filled the gaps between sections of my base foam last night using it. I all so use drywall compound like Mr Hill. I bought a 25 pound bucket for $12.00 or so 3 years ago from Home Depot. It was still good last night, first time I opened it in 2 years.
