It's not a good idea to do filler work over urethane surfacer, at the most a skim coat of polyester glaze is acceptable if the surfacer is sanded. The bond is not the same as on epoxy and you'll possibly see some mapping at some time down the road. Buy some quality epoxy or do the filler work over bare metal.
