What grit sandpaper do you use on primer for Kiwigrip 80 , 100 , 120 ?

any of those will be fine, it does not need a lot of tooth to bite. I have not had any peeling issues with even 320 sandedr topcoat

I'm using 150. I find anything more aggressive wants to tear up my tape lines.

for scuffing paint, i think 180/220 does a great job. The more aggressive grits do not "bite" as well into a super smooth/hard surface. The primer sands well with pretty much any grit.
