I'm not knocking your favoured company i think Rodella do very good work I'm trying to save the OP from wasting a lot of time and money by thinking he can fix his tube problems by overpatching! Looking at the pics of your tubes it doesn't look like they were delaminating as much as being rubbed up the wrong way. And therefore overpatching would be easy in terms of adhesion and attractive if skillfully done, which your clearly were
Fixing the worn out bits is as you have good material to bond to. Can I ask were the Sun damage parts colour faded or could you remove the top layer of the hypalon and expose the weave by rubbing with your fingers Say 2 inches away from the fading.
