If you don't need any repair work on the bumper I would just take the lacquer off the original paint using a very fine grade abrasive, then I would give it a spray with a couple of coats of primer followed by a couple of coats of paint then again finished off with clear lacquer.

As advised in other posts prep and prime before top coat, to get the best result. If you are just after a quick and cheap tidy up, you could get away with flatting with fine abrasive (600 or finer) then apply topcoat, although any remaining abrasive marks and existing scratches will show in the topcoat. If you do this, make sure that the new paint is compatible with the existing; some paints react to each other so do a little trial before spraying everything.
The primer is an important step in the painting process. It provides a smoothing and easily flatted layer over the base that the thinner top coat it laid onto. A topcoat is also semi transparent, so it is important that the correct colour primer is selected, assuming match to an original vehicle colour is important.
