: Was putting on a fill coat yesterday, and as usual having a fun time herding

: Anyone have good/bad experiences to report? Any favorite ratios, wait times,

Hi Dan,
I too wanted a quicker way to fill the weave. I'm using Raka no blush epoxy on my latest boat. I bought a qt. of their 900hp resin along with the regular 127 resin. The stuff is really thick. I used the thin stuff for wetout and the thick 900hp with the non blush hardener to fill the weave. It works great! The weave fills with less coats. I also use it for thickened epoxy mixes, seems to take less filler. Won't help much for your current System 3 epoxy but might for a future boat.
