I am under a dead line of about 12 days. Can you put a fast cure epoxy over a slow cure type? I need to put a final coat of epoxy over alot of sanded area of the outside seam that was freshly taped and some areas have exposed glass from the sanding. Can I use a fast cure over the slow cure to speed up the process? Also what is the best way to apply a thin coat of resin? Squeege or roller? Thanks Joe
