I used to spend hours faffing with one product or another but like you, as I've got older, I just want something that does a good job that I can stand back and admire. Gone are the days of clay bars, polishes, sealants etc. I only ever get products like that out now when I've got a specific issue in a particular area. But the best thing I've come across in the last 12 months or so that is readily available in your local Halfords isn't a polish or a wax but a shampoo. Autoglym Ceramic Wash & Protect. I'm sure there are other ceramic washes out there but this does a great job. You won't believe the beading and finish. With a decent wash mitt and drying towel as far as I'm concerned it's all you need.
