Rear lenses respond to a mild cutting compound like t-cut, but do it with a wet piece of old worn towel,circular motions, off the car if you dare.......then some good quality resin polish to seal them and keep them protected with the same resin polish.
On detailing or paint correction as some call it, I like my clay bar, bit strange when you first do it but gets rid of dirt particles...tree sap...metal particles.....overspray etc etc, then wet cut with Farecla G6 or another cutting compound of your choice depending how far you want to take it. Always a panel at a time.
Pro's can make an average car look stunning, but depends on how it's looked after that and where it's kept.
Got some Farecla UV wax and that's awesome stuff, I was told it was for GRP boats, but that may be a tall tale...............
But then it rains, gets mucky............start again............or just bucket wash it and slap some tyre shine on .......feck it ....that'll do.
