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.
Last time I saw the paint (Nov) didn't appear too bad (but was under 4 years of storeage dust)
I'll probably go with Megs-Clay/Megs stage-1/SRP (couple times)/EGP/couple layers of Colinite 915...All by hand... Pretty much same routine as I have done on my Pearl Grey Corrado...
Bumpers and the unpainted Rubber "body-kit" will be given a dose of APC and then a good few goings over of A-G Trim "snot" too!
i did mine by hand with the tcut with red stuff in.
Works a treat and brings it up nice.
Only bits to be careful on are edges as ive found it can go down to white either because the paint is thinner or more force gets put on it when polishing.
Just take it nice and slow it come up beautiful.
I use Autoglym HD Wax on mine. I give it a coat everytime I wash the car. If I've not got time to wax it, I don't wash it. Net result is super shiny paintwork that resists fading even in the middle of summer.
