Hi there All, Quick question for the list - I'm considering trying to use Fryolux solder paint to seal up my loco tanks (ie paint it on, assemble the bits and heat it up, ading a bit of extra solder and flux as need be). Has anyone tried using Fryolux before, and had good or bad experiences? Also, the number of warnings on the side of the pot don't bode well, is there anything particularly bad about it, or is it just like using lead solder and bakers fluid? One other thing, it says its grade K on the side of the pot - is this relevant, anyone know what it means? Yours, Rich. MODEL ENGINEERING DISCUSSION LIST.
