That sounds pretty nice having the extended time for a chemical bond. I just re-stocked with 105/207 for upcoming projects though so it would be a while before I have the opportunity to try anything new.

The precoat means you don't need to worry about the epoxy absorbing in any one area, so you can simply apply a lighter coat and not worry about starving the cloth. The sqeegeeing takes care of any excess, so runs really aren't/weren't a thing with the longer cure.

The recoat regime with the System 3 really does make the epoxy application a much simpler process IMO.

I'm refering to fill coats. Wetting out the cloth is not a problem.
It's the fill coats I'm referring to.
Sorry for my lack of description.

I've always been a fan of system three too, and have never worried about chemical vs mechanical bonds. Fill coat runs can be almost completely avoided by using the small foam rollers. Roll on a thin coat, tip off with a foam brush, walk away from it with few worries. The amount of fill coats often depends on the viscosity of your epoxy. For instance, general purpose system three is thicker than silver tip, and usually requires fewer fill coats. However, using a foam roller means a fill coat can be completed in about ten minutes, so in the end it doesn't really matter.

I started with System Three. Agree it is a good epoxy. At the time, it was very reasonably priced. They sold out, and the price went way up.

I used their Clear Coat epoxy. It was thin, and required two extra fill coats. A great wetout epoxy though. Not the best for fill coats.

After contacting a Tech at System Three about excessive runs ? He advised I apply fill coats while the previous coat, was still tacky.
That solved the problems of runs.

At the time, I was using the big black foam roller covers, that fit a regular paint roller.
Switching to the "Cigar" type foam rollers, improved application.

This last hull, I waited a little too long, between fill coats. Yes, the next day, I was scraping runs.
Not a big problem, but it could have been avoided had my timing been better.
