I would just do another coat of WGDGPS then. That's what I do with my truck, and it easily lasts from August-April. My truck is also outside 24/7, and I live in a place that averages 200inches of snow each winter.
If you really want to top with 845 then I would wait the 12hrs. Give the second coat of WGDGPS a try though, I think you'll be as equally happy.
