Yeah I think i will give that a go. I've just come back in from washing the car (spur of the moment thing hehe) and for whatever reason it beaded up lovely this time! I've given the bonnet and front wings another coat of wax, there's a very slight difference in feel between the areas with one coat and with two coats, so feeling better about the durability. Did find it quite difficult to get a thin coat and had to rub much harder than felt safe with the MF cloth to get a decent shine without blotchy patches. I guess if the paint itsn't properly clean it's not going to work very well.
Did notice what looked like water marks/tree sap which didn't come off when washed, quite bad on the bonnet. I think I will give the cleanser a go and am tempted to clay the car as bottom half is quite rough with small specks of whatever which can be easily removed with a fingernail but not by washing. Bit nervous about clay though as I have a feeling it could all go horribly wrong!
So I guess the full treatment would be:
Wash, rinse and dry.
Ta for the advice. One last thing, can I wash MF cloths in the washing machine?
