Hey everybody!
Not sure if anybody els has tried this but, I found this method and tried it out it works great. Here's what you need:
Q-tips
Acetone free nail polish remover
Tamiya putty (works best with tamiya I have discovered)
here is a gap in a figure. I cant sand it because of the shape.
first apply the putty. You dont have to warry about being to careful, but be as neat as possible.
After the Putty has dried dip the Q-tip into the nail polish remover. The more nail polish remover you have on thee swab, the more the putty will be sanded.
Sometimes You might have to scrub harder than other times but your end result is an evenly sanded line!
Hope you like it. I have found it to be a neccesity!
