Polyester Primers

You can topcoat it if you sand it with like 400, but I only go to 180 with polyester, then I always Put 2k primer over the top of it.

So do you only use it for the first round of blocking ? After you 2K what do you block that with and how many times will you re-prime and block.

When I did my Dart I only used 2K, I used 180 till i was pretty much dead straight, Re-primed and went 320, Then re-primed and went 400 wet, and 600 wet.
