Get a better wax
Meguiars #16 is an awesome wax! Only costs about £10 and can last 3-4 months in winter and 6+ in the summer.
What I would do it every 2-4 weeks over the next clouple of months is just give the car a good polish with SRP. Work it in well in thin coats and leave it 10 mins to set before buffing it. As SRP leaves a very fine layer of sealent down anyway you will be protecting the paint but only if you do it regularly.
Keep doing it every few weeks until you get the paint upto the condition you want it. You will be removing the fine oxidised layer bit by bit in very fine layers until you get the perfect glossy red you want.
When you got that perfect red then give it a coat of a good wax.

Then once every 3 months give it a good polish with SRP again and another coat of wax and your set for another 3 months
