why thank you gav :P megs tech wax indeed does have fillers in, its not exactly a very durable wax though, i do use it but only on 'customers' cars for a quick shine. if i was you id nip to halfords and get some autoglym super resin polish which also has 'fillers' in. then go over with the wax id also polish one panel at a time then remove straight away, do the full car , then in this weather i would wax the full car, by the time you have gone round leave it for 10 mins and remove with a fresh microfibre cloth. should do the trick , although as said, tech wax isnt very durable so most likly wont last long :(
