I used rubbing alcohol with cotton to wipe surface prior to installing. As you get to the rear legs as you apply decals in that area... Rotate legs from unfolded to folded make sure it's not causing issues. You will need to unfold and fold rear legs for a couple of them to make sure you get it on good.
Also keep a q-tip near. So you can push some of the corner tips in the cracks. I also use q-tip for the bends so there are no air pockets.
