Has the paint faded?
SRP by hand would give you decent results dude, but by polisher would speed up the process. Try a slow speed first on a finishing pad, if not crank up the speed and move to a more aggressive pad. Most machine polishing is trial-and-error IMHO. I'd also be wearly of using compounds on red, but a pro might go with a Menzerna/3M/Meguiars cut and finish with Menzerna Final Finish. But I'm no pro by any meens. Be prepared for your pads to be red by the end of it tho!
Naturally seal with a durable wax like Collinite 915/Dodo Juice/Finish Kare or whatever floats ya boat
If the paints already nice, just a good quality polish like Zaino Show Car and again with the wax. Keep ontop of it with spary waxes after each wash. Should give protection for atleast 3 months, have seen reports of some of the above waxes lasting 6+months but I've no experience of that, only what seen on tinternets.
Where in the country are you dude?
