ok here we go, primer filler is applies to be sanded it is also made to fill scratches from teh sand paper, and low spots, you block primer to get the panel straighter then a arrow
primer has to be sanded if it is not nothing will stick to it
thefirst 2 coats of primer shuld be blocked using 120, then re apply 2 more coats, wet sand the primer with 320 then 400 then 600 then 1000 going that route you will have no scratches i have been doing it that way for yr`s and the end result is well worth it
sealer is made not to be sanded it is the fial product before base, if ya have any imperfections in the base let it dry then sand it with some 1200 re apply the base, the ncs sealer is a 2k product most everything out to day is the 2k product
don`t get to confused prepping a car for paint is a long process, every part of the panel should be prepped smooth no shinny spots if ya see any use a red scuff pad
oh ya, if ya sand primer with let`s say 240 then sealer base clear you will see every scratch and it will look like crap so sanding with a finer grit will make sure you have nothing coming back on ya
preping is everything, poopty prep work end result poopty paint
