The powder coating MMC uses isn't robust enough to survice the Easy-up hood clips.
Once it has started to chip at the top it seems then to come away, perhaps water gets in.
With the 2009 Roadster I did look at buying a new set, getting them stripped and then hard anodised, but the sale solved the problem, BUT the 2014 Plus 9 is starting to show it will go along the same route. So perhaps I'll re-visit the idea.
Actually cast stainless would be far better...but VERY expensive as a 1 off.
peter where did you put the extra cylinder.
