that's the way I look at it... the garage industry is still one of the biggest rip offs (IMO).
it's a bit like detailing.... over the past few years there has been a massive surge of "professionals" out there, and from what I see, most if them are hopeless with a machine polisher... I've had to fix 5 cars that one of the local guys butchered...
they think running over a car quickly with a heavy compound is all that is needed, cover it all up with a filler glaze, then take some pictures at the angle which all cars look shiny and defect free then they are stars..... (in case you wonder, it's the stand from the front or back, and take the side view picture)
it's a shame, but humans always love to con each other... and happens in most industries too...
