I'm trying to remove five years of tar spots and sap, and will clay bar it my self. After that I'm still going to be left with five years of never been hand washed swirl marks. I'm based South of Cambridge, is there anyone off the forum who is trusted/less big company name prices? Or just a guy who I can trust to perform a top notch job. After this I should be able to keep the car in a topped state of goodness. Anyone...?
