dear i doubt its avilability in pakistan but autofinesse u can get from pakistan
and pls dont misunderstand its just resist to scratch but its not totally scratch proof
car in workshop now for repair and going to replace both doors but just for experiment painter tried to scratch / remove paint from effected doors and he faced real tough time to remove paint from some area 
i belive every paint sealant resist to scratch so autofinesse 6 month strength sealant called power seal will also provide similar protection
