After polishing, carefully touch, and then put the pit to do the label, the tag is filled with a putty with a big up place, and then the massive hyperplane as a whole, then hang the line, it must be super again and the putty should be thick enough, then still Use coarse grinding because sandpaper carefully polishes the rough putty.
Coarse grinding is unsuitable, leaving a putty at the grinding of 120-240 sandpaper. Conditions can apply a layer of toner fine grinding index layer, no condition can be coated with eye ash, the leaf coating fill the eyes must be very thin, and then use sandpaper 320, this step is to deal with sandpaper Mark minimum, fear of sandpaper mark Too heavy, spray primer, or will be in the future.

These two lines are what we want, so it is a natural one.This is my own tip.
