I am a big fan of Poorboys. I did use AG SRP but i found it to have a slight cutting action which the Poorboys Pro polish does not have. I tend to give my car a good polish twice a year followed by either black hole or white diamond then layer it with Nattys wax. Or an alternative to wax is the EX-P sealant which i put 2 coats on leave it a few days then a couple of coats of wax and that will last throughout the winter. SSR.1 is good for light scratches. what colour is your car as there are a few combos of products you can use, white diamond and nattys wax, black hole and nattys blue or red or both. Bast thing about the stuff is you can use it ib direct sun light even in the summer. Super slik and suds is a very good lubricated shampo and can be bought in bulk but 1L will last me 18 months and i was my car every week. Bold and bright tyre dressing is water based liquid and can be diluted but my must buy is the wheel sealant its just the best on the market apart from the new nano or ceramic coating which cost a fortune, i find 2 coats last over 3 months. have a look on there uk web site or the poorboys forum.
