I had PPF fitted and the very few chips I have are more noticeable than without it. I can love with it.
If I'd had more runway I'd have had a crack with this:

I had great success with this stuff on my Valencia Orange 1M previously which had hundreds of chips on the front (paint would chip just looking at it!). It's not as good as a toothpick/pencil sand/clear coat but it's less chance of messing up too as it can be removed easily and you can try again with it.
