I just picked up a DRGW F3 AA set from 2014. #38702... Yes the proverbial 3 blinks of death on the smoke units. I have fan motors, I can solder, so no worries there.
My question is about the gasket Lionel has applied to the underside of the shell to seal against the funnel from the smoke unit. I had used some roadway tape that I bought at my LHS. Ten years in a bag, nope can't use that anymore!
What are you guys using to make gaskets?? Thanks!!
