Looking good Nath. Can i ask if you followed the Super Resin Polish with anything else like a wax or something ?
Reason i ask is that although SRP has fillers and polish ingredients in it, it doesnt have anything you could consider to give any protection to the finish. It would be a shame for you to spend 5 hours on the car for the finish to look that good for 2 weeks and then be back to square 1.
If you want to stick within the AG line, there is Extra Gloss Protection which is a sealant best used over SRP or there is HD Wax which looks expensive but will last (the actual tub) for years.
Of course there are hundreds / thousands of other options depending on what you want to spend / what you want to achieve. Collinite 476s is a long lasting wax for around £15 but imo it doesnt add anything to the look of the car. PoorBoys Natty Blue is around the same but gives a slightly wetter look (doesnt give the ame durability though).
