Hi!
As "High Plains" says! Sand it down with 1200 wet and dry sand paper and then spray it with 2-part acrylic clear.
I have done this many times.
If not satisfied ...sand it down with 2000-2500 wet and dry papper and then use and of the automotive paint polishing compounds available.
3M Finnes-it is just one brand, there are nay others-
Just wax doesn't remove any scratches.
