Also no, but I'd seen the reviews, read around and was tempted to try it.
I've got a couple of singular and tiny paint chips on the sides of my car. It looks like the product is great at think or point defects, but struggles with larger (1mm plus) stonechips.
Some links to a camaro forum with pics.
If you apply it to a large area of chipping, to seem to get a mottled effect. At first glance probably better than lots of white showing throuhg ona dark colour, but certainly not back to new.
I used it on a decent sized stone chip on my bonnet and it's a huge improvement but don't expect a miracle.
It's really easy to use and has been a couple of years and hasn't fadded or changed.
I have used it on a massive amount of rash on a Black commodore. Loved it. It makes life so much easier than trying to paint using a little pen.
That said, its not perfect, but neither is the pen unless you apply, sand apply sand etc.
