Plans schedule filled the spar caps nicely. As previously laid the tape straight off the reel, cutting with shears. Just laying it on the painted resin/previous plies stopped it moving around enough to remove the red and cross threads. Wetted out with stippling brush and straightened with a 3" segmet of a wide toothed comb. 0.8kg of resin used.
Ripped up the masking tape and applied duct tape, then peel ply over all. Next time just mask the foam with duct tape so I can leave it there.
