I'm refinishing & re-insulating my doghouse and the gasket that goes all the way around if pretty messed up in a few places. Its also shrunken over time and is about 3" too short to make a consistent seal.
I'm sure someone here has replaced theirs it at some point during a restoration. What did you use?
I've been looking on Steele Rubber, Mill Supply, McMaster-Carr, etc and can't find anything that has a large bulb on the top and a smaller one on the side like the original.
