If you have a silver or gold car, you might see some stripes in there, so
what you want to do is follow up with some vertical passes.

Repairing and retexturing a Ford Explorer bumper cover
This video demonstrates, from start to finish, how to repair a textured
plastic bumper cover using a hot air plastic welder. After the plastic
welding is complete, the dents and low spots in the bumper are filled with
epoxy filler which is then sanded down to match the original contour. The
bumper cover is then retextured with MicroTex texture material from
Urethane Supply Company. Finally, the bumper cover is painted with Bumper
and Cladding Coat so that it matches the original color.
