There is also stuff called 2 Hour Finishing epoxy.

I've done a few projects with it. You have a good 45 minutes to an hour "working time" to 'card' the resin through the glas or silk or CF (very carefully! It throws stray fibers) to where it looks like there's no resin on the fabric. (Carding - using an expired credit card or similar to drag the liquid resin into and through the "fabric", then scrape the collected juice into the mixing cup, and a wipe with isopropyl alcohol to clean the card edge for the next wipe.)

Finally, laying paper towel across the epoxied surface can draw a bit more resin out. Blot it down, then peel it off like masking tape, folded over back onto itself. The resin is heavy. The "fabric" will be there in any case. Getting the "weight of resin equal to the weight of fabric" is a basic rule of thumb. ANY excess you can card or blot out is weight the wings won't have to carry.

The 2 Hour stuff deserves a full 24 hours to let cure. After that, a light dusting with 360 or finer should be a good start to a smooth surface. From there on, it is basically a filler and clear build-up to color and gloss coats. ....But without the first coats soaking in and disappearing...
