I have been getting more core in, and the advise has helped. I pulled 9-10 lbs on the next core install. I went big on last weekends and only pulled 2-3 lbs, but i think because of the size of the area my pump couldnt pull hard enough. I dont know, but its down really solid and conforms well to the contours.
All i got now is one more bag on the piece in the bow then on to sanding off the backer cloth, filleting, and glassing over.
One problem i have realized is when coating the balsa with epoxy in the tape areas is its hard to clean for amine blush without getting the bare wood wet. Trying my best to clean the amine up between layers/stages.
I have discovered that using adhesive tape can tell you a bit. If the tape doesnt stick you have some blushing/amine blush on the surface. I can kinda feel it by hand, and cant see it at all. I have been using a toilet brush, scotch bright pads, distilled water, and lots of paper towels to dab it up. It sucks that i cant do it all in one process, so dealing with the blush is what comes with epoxy. The peel ply is awesome for epoxy since it "peels" away the top layer with all the blush leaving a perfect paint, or next layer surface. I need to use it more then i remember too.
