Just to Update this, I was sick of looking at the hand prints so had another go,
After trying all listed above i went back to square one. Used petrol to clean them off, (I'm aware some ppl are against it but ive never had a problem)
so cleaned them off with a soft cloth and petrol, Powerhosed the car, then washed it with Hot water with shampoo, Dried it, waxed and polished it.
and FINALLY their gone, months they've been there. Their about 95% gone i reckon one more treatment will do it but as you can see, its a big diff.
Im happy anyway
