that looks more like the AG product leaving marks on the surface maybe?, i treated mine about 8 weeks ago, when i sprayed it on it left water stains/marks, i went back over it with the cleaning stuff and sponge, then re applied the protection with a soft sponge rather than spray and the marks were gone.
how do you clean the hood normally? i just use the hard white sponge that came with the AG kit and use warm water with a tiny bit of car shampoo in and hose it off. it could be that if you drop the hood wet/damp you get the marking maybe? i think its more luck than judgement that ive always left the hood to dry before i drop it.
