Im glad you posted this advice Gavin.
I'm still VERY wary about giving advice about PF touchup/restoring.. as the methods i use are VERY different to what most other people use, and i dont consider myself an expert at this at all, to be totally honest. I just like the auto acrylics because i'm used to them, they work well for me, and id hate for some one to ruin a good PF if my tips didnt work for them. (i only replied because i was asked.. as were you).
Dont get me wrong, im always happy to help others out if i can.. i just want to be sure the advice i give is good
