You shouldn’t really because the stainless can pick up ferrous particles. These then float into the pool forming inclusions, you can then end up with rust spots.Can I store stainless filler rod in a mild steel tube, will this have any effect on the filler or will it be ok. Thanks
There’s arguments in the aerospace industry that you shouldn’t use PVC tube because of chlorides or something believe it or Not.40/50mm plastic waste pipe is best, with a solvent weld cap end on one side and a screw on access cap the other. You can make a few up for 15 quid or so.
