Expensive - but more than just a detailer
                    I've been a fan of Polish Angel stuff for a few years.  I've used Rapidwaxx a few times and I use it like a treat for my car, but thats expensive.  Decided to try Presto and have been very impressed by the results.  Typical Polish Angel, a very waxy feel to the liquid, but it goes on so easy and buffs so easy it is a seriously luxurious product.  Still expensive, but a lot cheaper than Rapidwaxx, and I don't see the benefit of paying any more.  Paintwork beads beautifully after application.  
Honestly buy a bottle and try it - I don't think you'd be disappointed.
