Don't believe a word of this, however IF it takes you just half an hour to whip round with some wax x 2967 that's nearly 1500 hours of waxing. Given there's 48 half hours per week = 336 hours which means you have spent a total of 14 days waxing. Take an hour to wax & you have spent 28 days waxing, nearly a month. Mind you maths was & still is my worse subject.
I was once told that too many layers of wax means the suns rays get magnified & can burn the paint or at least accelerate loss of colour. Think all those red cars that go pink within a few years.
