Boat Builder Central

Just finishing up my project and realize I will need 1 more quart of Sterling topcoat. Interior of boat is completed, transom completed. 2 coats of topcoat on hull sides and I will need 1 more quart to do final 2 coats but Sterling is no longer available here and I haven't been able to locate any of...

Does anyone know the minimum required temperature for Sterling top coat. I am finishing up my FS 18 and need to paint the outside of the boat. I am working in an unconditioned garage and am concerned about the temperature. I can't find the temperature range anywhere. Thanks.
