If your using the open formers that come with the clarke 12t bender it does'nt matter what you do with the tube it will always kink or go flat. You need to use high sided formers like the hilmor conduit type, how ever the biggest hilmor former is 42mm. You still get minor kinks that are 1mm deep but can be over come with a little filler and paint.
