Interesting stuff mate. My query is about how you ensure you dont a) sand down too far when wet sanding the 1,000 and how you ensure you dont burn through the paint, especially on the edge of panels? Do you measure the paint thickness somehow?

I know a few paint shops who do cheap paintwork and generally subscribe to the ethos of just whacking the paint on nice and thick and then getting finish by buffing it off. Would you agree that as long as the paint is deep enough you can sand/buff back to a proffesional finish?
