UK - England
just a quick tip/reminder that I learnt from detailer (who said actually to not use covers…even good ones) that if you must use one (I got the classic aditions one) make sure its a) spotless so you dont drag grit etc across paintwork b) totally totally dry (use leaf blower if u can, no joke!) and/or leave a day or two in garage after before putting cover on. Apparently water is still around on microscopic level and putting a cover on top isnt a good idea until completely dry.
just passing it on;)
