-PE blade from Scale Motorsports--Top Studio & Tamiya have them also
-saw has 0 set--good news: thin kerf, maximum control, doesn't skate bad news: takes forever
-tape lets you know when you're close enough so you don't cut into the body
-after color/clear coat, mask & chrome paint--may need to run blade through kerf if paint/clear too thick ( haven't need to do this when airbrushed)
