I just used the mazda paint pen to fill in some chips on my 09 mazda3, copper red. It doesn't have a narrow tip like the one you posted above, more like a fat sharpie. Which made it quite difficult to fill in just the chip. The other end of the pen is a clear coat. Honestly, I am not too impressed with the job I did. It looks like darker slightly raised spots. I am hoping I can smooth them out some how, perhaps with high grit wet sand paper? I think for future chips I may cut the felt of the pen narrower.
