Shoddy, if you don't use a polyester putty to finish your filler and are sanding it with 180, you don't know what you are missing!
Polyester putty is the ONLY way to go to finish filler, the "skim coat" if you will.
Let me repeat Erics point, there is NOTHING, but NOTHING wrong with using polyester putty. We are not talking about some junk out of tube for goodness sakes, we are talking POLYESTER putty. POLYESTER just like POLYESTER filler such as RAGE. They are one in the same with the basic difference being how fine the talc has been ground.
TRYING to fill 40 or God forbid 36 grit scratches with ANY primer other than, you guessed it, POLYESTER primer is WAY, WAY WAY out of line. A urethane primer is NOT going to properly take care of those deep scratches.
120 or 180 scratches will easily be filled by most any urethane primer with no shrinking IF the primer is applied properly.
