I would disagree with you on the deep chip statement. I've used their system on three vehicles. Where you run into an issue is large chips, not deep ones, and only when dealing with colors like white platinum. If their magnetic has some flake in it you should be ok.
What helps is to build the paint up in stages, dab and smear more paint every 10-15 minutes until you have built the chip above the paint. Then when you swipe the solvent on the applicator, be sure to not press down. You are only trying to take off the paint that is past the chip. You may need to apply more paint again and do the solvent step another time, but it is pretty effective.
