ok my car is about a year and a half old,never really waxed it or anything,just an occassional wash.now i feel like actually taking care of it.i notice that the surface isnt smooth,so i was wondering about wetsanding it?ive washed it,and applied a wax to a small spot,but it still wasnt smooth,so what should i do from here to achieve a nice,smooth and shiney finish on a budget?and for the records,idk anything about cleaning products...
