I wondered if anyone had any suggestions as to suitable mastic/gunge/sealant to use to seal the crevices at the bottom of the built-up smokebox of my Elidir. I guess I am talking about gaps of up to 1/64" wide? I had a look in Halfords at good old Gun-Gum and the "own-brand" equivalent but both require heating to exhaust operating temperature before and after application - Possible, but not too convenient too do.
