Hi there fellow biker: I live in Cape Town and suffer the same maladies re: clear coat chipping. It's something we have to live with here living by the coast I'm afraid – well that and the thieving of one's machine if you not careful! OK, there's a product called ACF-50, try and see if it's available in the UK, this stuff works a treat, but it's pricey, R250 a tin (about 14 squid), the Canadians make the stuff, so it could well be sold your side ... Good luck!
