IMO dodo are one of the hardest produts to use IMO,poor boys is the easiest I have ever used and that's the hole range and well priced to,and I'm with rob auto glym is not good stuff

And as Steve has said keep on top of the polish and a long lasting wax,I put a 3 coat wax on just over a month ago and today the car was the dirtiest it's been since I had it and washing it was like I done it only 2 days ago,it was so easy to clean,oh and buy a good wheel sealant
