7 day window

Hello fellow SPI enthusiasts. Sprayed my first SPI epoxy this weekend on a vintage car over stripped metal with some filler - no problems and very pleased with the results. I let the vehicle sit outside for six hours on a 70 degree day, with off and on sun, then pulled it inside. I won't be able to lay down urethane primer until NEXT weekend. I can sand, scuff or leave alone. Your prep advice?
 
Usually after 3 days I sand it just for peace of mind. If over 7 days it will need to be sanded for sure especially after being in the sun. I think one full day in sun equals 7 days in shop.
