What flexible filler to use on motorcycle fairing panels

[mangocrazy]

I've recently acquired a damaged top fairing for my Aprilia Falco, so I can modify it without feeling guilty about damaging an increasingly rare original item. The fairing has some crash damage (it slid down the track and abraded one side) . At one point it has gone through the panel, but most of the damage is surface abrasion, to a greater or lesser degree.

I'm looking for recommendations for a filler which will stick well to plastic and is genuinely flexible. Even to mount the fairing to the bike it has to be flexed over the inlet 'snorkels' that feed the airbox, so any filler will have to cater for flex. And I'd also like it to be fairly easy to sand...

Photographs show it more clearly than I can explain. First off, the damage on the RH side of the top fairing:

As you can see, there is surface abrasion, and one spot where the damage goes through the skin.

One of the headlamp mounts is broken and there are a few screw holes that have been enlarged and damaged and will need re-work.

There is a >PP< stencil on the inner fairing, so I presume that means the material is Polypropylene.

Any suggestions?
