I received my Autosharp Pen yesterday from the group buy coordinated by Vrm Vrm. Didn't have too much time last night, so I just tried it on a small chip on the wheel well lip.
I prepped it with rubbing alcohol, to get the Zaino off, and smoothed out the edges of the chip.

Application was easy and the color match on my red S was spot on. I will need to put another "coat" or two on to raise it up to the level off the surrounding paint.

I also order the clear coat pen - I will report on how it works in a few days.

I understand that vrm vrm has more pens. PM him if you are interested.
