Awaits flaming - I spray Demon Shine after a wash and rinse and then blow my car with a leaf blower. Takes about 10 minutes and looks great
Nowt wrong with that, it's what I do
Meg's quick detailer is very good and will do just as well as 99% of any other quick detailer available
Also
Dodo Red Mist is not strictly a quick detailer as it has no cleansing properties at all, its basically a quick protection top up
Saying that though I love the stuff and is one of the two Dodo products I would recommend.
If you have a slightly dusty car or water spots after washing use Meg's detailer, If you have a clean car and want to top up wax etc use Red mist which would probably gives a week or two protection
