It's to thin to fill pin holes or level minor imperfections.

I will admit I have no cue how to paint and it to turn out worth a poop, but is high build a short cut to filling all the voids and well, pin holes, so you don't have to have a "paint ready" finish? Isn't fairing and sanding surface prep for painting or am I missing a short cut?

High build is usually used after fairing to help achieve a really nice finish. Think if it as a much lighter weight spray/roll on fairing compound.

There is no primer out there that will fill large pin holes. ySystem 3 will fill very minor ones. Bur if your looking for a primer to fill a 1/16 larger on your out of luck.

Ask Jeff what he recommends.

I can't get S3 to fill my tiny pin holes, have to use Quickfair or an automotive product in a tube called Khombi's super putty. The putty is great with the tiny ones, but not too practical for big areas. I'd love something you can just role on. Someone here recently mentioned using a roller on their fairing mix, which sounds interesting.

I recall someone on here talking about a product made by 3M (I think) that they found at the auto finishing store and thought worked great for filling pin holes. I don't know how it would compare to Kombi putty, but it sounds similar.
Is there a good way to avoid creating pinholes? I assume the problem is caused by having air bubbles in the fairing mix?

Found it- 3M Glazing and Spot Putty

Hmmm...having trouble getting a perfect result, are we?
Sounds like other boat builders...in the range of 90%. The other 10% just give up. :D

A guide coat is the only way to go if you want results. S3 is not a filler, and I wouldn't mess with adding things unless I checked with the manufacturer. In my case (and I know of some others) I ended up using S3 as the guide coat. You think you've got it faired, and then you put on the S3 and say, OMG this sucks. Then you sand and fill and sand and fill and put on another coat of S3 and say OMG this sucks but not quite as bad. Rinse and repeat.
A trick Cracker Larry used was water but he worked outside. He just ran a hose over it to find the holidays. It certainly is cheaper and quicker than a guide coat.

The bottom line is that unless you are a pro, this is a time-consuming and frustrating process. In the end I felt it was worth it and I was glad to have spent the time. If there is any self-leveling magic trick that you can just roll on and proceed to the topcoat after sanding with only 220, I'd be surprised. Ask a body shop; that's not what they do.

There is a truck... liquor. Just drink enough and it will look GREAT. Don’t believe me, go to a bar and do some A/B testing of my hypothesis.

Here is an article on pinholes and one method of getting rid of them before primer:
