Which one is more aggressive? Yes i am aware that UP does not have any wax in it and D301 does. On my Black car I always get some unwanted microscopic scratches and wondering which polish is least aggressive since they both do the job for me.Using UP is additional step since car has to be sealed (waxed) afterwords unlike D301.In either case I still use Gold class paste wax.I think my scratches are induced with Cal duster. Time to wash it.
Thanks
