The packaging notes that this product can be used with more vigour to repair deep damage, but touch-up paint would be required afterwards. This confirmed our practical impressions that care would be needed on the light scratches we had in mind. Used gently, Turtle Wax’s Safe Cut did the job well, but applying it with a heavy hand resulted in too much paint coming off, leaving the test panel with a slightly duller finish than we’d have liked. And the price was high compared with that of our winner – so while the Turtle Wax is good, it’s not the best here.
