up here in Toronto it is getting pretty cold fast. I drive my car year round and was wondering if I should have it detailed prof before winter for some added protection (wax). I use a spray on wax in the summer after weekly washes. Does wax help at all for protection and if it does would a spray on wax work just as well as something a prof detailer would use?
Also, what are the ideal temperatures for the application of wax? I know you are not supposed to add wax on a car that has been sitting out in the sun but does the same rule apply to a really cold car?
