What is best for a newbie without a very steady hand to use as a tip (1.8 or 2.2mm) for the FeatherFill? I am not great at going slow and steady with my gun and trying to avoid the heavy spots & missed spots that I experienced with the SlickSand. I am getting better each time but this is an art which I am not great at. Thanks!


First off stop using both products, use one or the other, they are similar enough.

Second, if you have to poly twice your body work was not even good enough to start priming

be diligent in your body work, Featherfil 3.0 air gunsa, block with 150, use a flashlight find any pin holes and fill them, if you found a spot that needs a little more work go ahead and get that spot up to par, SPOT prime with featherfil any body work you may have had to do, block those spots with 150, again look for pin holes, when everything is good go ahead and block with 180,

now you should be ready to prime using a good 2k urethane.
use guide coat in between each step.

A high-build Urethane 2K won't fill those tiny pinholes?

The larger the tip, the heavier the coat applied, the more chance you have for pin holes.
I have never really had a problem with pin holes with the Feather Fill G2.
Using a quality guide coat will help you detect any pinholes.

Remember the idea is to get the panel straight with a minimal amount of material.
Here I had to replace a quarter panel with another used one in better shape:

Stripped the panel and shot two coats of black epoxy. Then lightly block sanded the panel with 150 grit. You can see it has lots of issues.

Hammer and dolly for the worst of it then shot three coats of Feather Fill G2 over the entire car one time.

Guide coat, block sanding, filler, 2k, more guide coat, more block sanding after that.
