This week I bent some 5/8 OD tubing for the first time using Cerrobend. I have had a chunk in stock for many years and only just got round to needing it. I plonked it in a sauce pan of boiling water and it melted very quickly I then poured water followed by molten Cerrobend into my bit of tube . When it cooled off I bent the tube without any collapsing in a fairly crude bending jig that does not have proper grooved rollers. When finished I just popped the bent bit of tube back in the saucepan and melted the Cerrobend out.
It really dead easy.
