My bumper surface is uneven and not as shiny as rest of the car after reapinted?

my bumper got some dent and some scratches and I decide to have it repaint. after it is re-painted. my bumper surface is uneven (on the area where it had dent) and i feel the whole bumper isnt as shiny as rest of the car after reapinted. I noticed the surface is not even from certain angle when the light reflect on the bumper. i guess it may prolly cuz by the material they used to fill up the dent. is there anyway to get rip of the uneven surface, and make the paint as shiny as the rest of the car ? Car is only 1 yr old and I intend to keep everything new.|||Sanding the surface before paint has nothing to due with the quality of shine. Sanding the surface only give the paint a texture to bite into so in the future it wont peel off. the only reason for a dull surface is either the clear when they applied it had to much solvent and dried to quickly and had a die back. THe undeven texture in the previously damaged area is probably bad body work. the uneven surface is there to stay unless they will do the work over again. the dull bumber may be due to a sevear amount of orange peal which is easliy fixed by sanding down the high areas and then buffing and polishing.|||bumpers are plastic and are very hard to paint. that being said, the bumper was probably not sanded properly before being painted. take it back to the shop and complain (especially since you plan on keeping the car.) for future reference, no matter what happens, aftermarket paint is never as durable as factory paint and will chip more readily now.
