i think that's why the one mirror cover had many bits of dust stuck to it when i did paint them the base started to bloom so had to heat it up with the heat gun i then setup an little blow heater that's what i think put the dust on the one cover
you can see it in this pic in the reflection of the lacquer

going to try with the spoiler now had the heater and extractor on for 2 hours so should be dust free and warm enuff not to bloom
i bought the anti blood just in case im not sure on the price difference i think there both £6 for 5l
we will see how i get on later 🙂
