Tips for barrier coating with Interprotect?

So my boat has been out of the water since last October. Upon hauling her last fall, I noticed a band of thousands of little (BB to #2 pencil eraser sized) blisters to about 30'' below the water line. I removed all of the bottom paint, and the gelcoat to fiberglass in the area of the blisters. The bottom is dry (verified with moisture meter) and I would like to barrier coat soon. I have read Interlux's Interprotect instruction manual, but does anyone have any additional tips/advice? Has the interprotect been "kicking off" too quickly on 90 degree days? Would rolling on a coat of low viscosity resin (MAS or similar) help seal the fiberglass, or would this be a wasted step?
