Sprayed 2 rocker panels that were stripped to bare metal and 180'd, than cleaned with SPI Water Based grease n wax. Sat at least an hour, than sprayed two coats of black epoxy mixed 1:1, ten minutes apart. finished spraying at 7pm, and it was about 67 degress in the booth. Left heat on all night about same temp. How long should I safely wait to spray my 3 coats of SPI Primer over the top of the epoxy? I know metal temp is generally 10-15 degrees cooler than air temp, so I want to make sure I give it enough time to dry properly, before spraying my primer. I know waiting longer is better, but i also have to keep this project rolling along, as I am on a time schedule, somewhat.
