Last weekend the upper wing skin of a 235/320 as bonded to the main spar, I noticed that after all the settle one of the wing skin did not stay on the cradle somehow the trailing edge is now at 6 degrees "down" instead of aligned with the cradle to give a 1 degree up for the desired washout. the aircraft is inverted in order to build the wings.

At this point the spar and nose ribs are bonded to the skin, there are no wing ribs or anything else has being installed yet. The question is what is the best way to get the wing skin to conform with the cradle, it takes about 15 to 20 lbs. of weight on the trailing edge to bring the wing skin to conform with the wing cradle, is it safe enough to heat up the wing skin and spar to move it a little bit?.
