Framerate,
I will have to admit, I didn't use boiling water. I stuck mine in the oven, on a low heat, till they started to go *just* soft enough... But you have to handle them carefully or it can all go very wobbly.
However, this topic came up last year and another poster on that thread said he did his using boiling water, which sounded like a better way of doing it. Which is why I suggested it above, though in my case it is an untested method.
Myles, this is about the wind deflectors which attach to the side of the windscreen in the sidescreen hinges. Nothing bolts on. WIMPS are something else again.
