I dont cover in that method where you seal the perimeter and shrink the middle (over solid balsa structure), I said I just heard about that way. I said I do tack it in the certain areas and then go back and tack it everywhere inbetween (over open bay wings). I have never built a plane with solid wings yet. After it is tacked all the way around I shrink it down with a heat gun and iron it down to the ribs. I dont read the instructions on monokote so I dont know how they say to install it. All I know is my meathod seems to work and thats good enough for me.
