I had my rear bumper replaced and painted. The paint match is very good but the paint seems to be a bit rough? I was wondering if I should polish it or use a clay bar? However I'm not sure if it's too soon to do so? Any advice on this matter would be most apperciated

Thanks

 

Ya, take it back to the people who did the painting and have them work the roughness out.

 

this is a clay solution, but i agree with whaler that you shouldnt have to do anything- they should fix it.
they will probably clay it for you.
make sure it has no scratches when you go to pick it up.
the paint should be cured by now...
my only q to them is whether they clear coated it or not. (sometimes rough paint indicates overspray which usually happens without clearcoat... your car had clearcoat when it was new and should after it is repainted, imo)
