Currently, Collinite 845 Insulator Wax is my go-to wax. I’ve tried others but keep coming back to Collinite 845 and have been using it for probably 8-10 years. It’s the liquid form of Collinite 476S and as it’s a liquid, it’s easy on, easy off and has very good durability too; applied to ‘clean’ / decontaminated car to ensure good bonding to the paintwork, I find it gives a good 6 month’s protection before it needs to be reapplied. It can safely be used on alloys, piano black plastic trim (not black plastic with a grained finish though!) and headlamps / tail lamps too. At around £16 - £19 a bottle which lasts ages, it is very good value too.
After washing using a safe wash technique (snow foam, three bucket method and ph neutral shampoo, lambs wool wash mitt, blow dry with warm air dryer), I apply a thin coat of Collinite with a foam applicator pad, and leave 15 - 20 minutes in warm weather (but not in full sunshine) to cure and then buff off with clean microfibre cloths, turning them frequently. I then apply a second thin coat to ensure full coverage in case any areas were missed with the first application.
Edit; @Carl_45; when you’ve got your car and you’ve spent time and effort making it gleaming and super shiny,
never ever let the VW dealer wash it when it goes back for servicing / warranty work, unless you like the ‘scratch n swirl’ look for your car’s paintwork!
