I use RM43 or Roundup in weedeater areas and on unused portions of gravel driveways. Everything is killed and dies off but spurweed, crabgrass looking weeds, and several broadleaf weeds grow back in full force a few weeks after the killoff. Is this a good choice for late spring/summer pre-emergent? I realize now I need to use this late winter or early spring but since I'm beyond that what about this year?
Using the Prodiamine 65 WDG (Generic Barricade) should be fine to use for prevention as long as it's down at the right soil temps, and labeled safely to apply on your turf type. If there are no roots of any trees or other desirable plants nearby/within 5-10 feet of where the gravel is, he could use a soil sterilizer like TVC with roundup/rm43 to kill what's there and prevent more growth of anything for a while.
