I agree mate, I absolutely loved finishing a panel, standing back and comparing it to an untouched faded panel alongside it. It was a hell of a lot of hard work, but it's the best paint restoration I've ever accomplished, so it just had to be shown off lol.
Thing is, it wasn't only polishing i did. The process i followed was:
1) Wash and dry
2) Clay bar
3) T-cut (original...couldn't find a yellow one lol)
4) Megs 3 stages i.e. Paint cleaner, Polish, Carnauba Wax
5) Poorboys Nattys Blue (Carnauba based wax with extra UV inhibitors to prevent paint fade in the future)
All of the above means going round a panel a total of 15 times before it was finished! Hence it taking 2.5 hours or so per door lol
Now i just need to keep applying layers of the Poorboys UV inhibiting wax every month or so to keep her looking top notch!
