Anyone used PPF on their Griff?

[seaside]

I tried searching but didn't find very much so here goes...

Having recently had the body work on the Griff redone I would like to keep it looking as good as possible and as we all know stone chips on the Griff are a perennial problem.

As a result I am curious if anyone has used one of the newer Self-healing Paint Protection Films like Suntek or Xpel and what the experience/thoughts are?
