My paint is silky smooth, no need for any fall out remover on there, but I look after my paint.
It's regularly washed, machined and highly waxed.
The whole detailing business gets on my wick. Everyone is a detailer, most wouldn't know their arse from their elbow.
The market is saturated with products, 85% of which are near identical to each other.
Most only ever see pics of work people do. He'll I could Photoshop a car to make it look new, I take all pictures with a pinch of salt.
So remember though I've colour sanded my car ;)
