So I washed my car yesterday and tried the Meguairs wax. It seemed to work well - the results were certainly highly reflective, although I did notice a few swirl marks in certain places that I couldn't seem to remove, but I could only see these at certain angles and in very few places. The car has been in the garage overnight and when I got it out this morning there were swirl marks all over like an echo of where I'd first applied the wax! What have I done wrong??? At the time, I used first a cotton cloth and then the meguairs microfibre cloth to 'wax off' and it looked fine. Its like the early morning condensation on the car has revealed these marks. Does it matter what I washed the car with before I applied the wax? It was a 'wash and wax' concentrate. Should I have used a polish before wax?
