Why don't you just use a wax like Collinite? I use this and apply 3 layers every 3-4 months and it still beads and shines after each wash as though I had just applied a fresh coat. These waxes aren't durable at all, they only last a couple of washes meaning that you have the wax the car most weeks like you said. It was a bit painful to read this: only downside is your car has to be semi clean otherwise you wax over the dirt but i found a solution to this use meguirs scratch X to remove the stubborn grime and grease, then use the smart wax this leaves AMAZING results i own a white glanza and the amount of Firstly products like Scratch X should not be used frequently, and I certainly wouldn't be doing the whole car in it due to the way it works. It's made for getting rid of obvious scratches, not the swirls on an entire car. Using this frequently will cause long term problems with your paint. A car has to be 100% clean or else you're just rubbing any dirt that's on the car into the laquer which is then causing the swirls etc. Please don't feel I'm criticising, just purely trying to help you out. I have done a lot of research into the whole process and I'm trying to point people in the right direction. Nice to see another cleaning freak though.
