I had my summer home, in Connecticut, repainted last year, by a professional. I now have 2 gallons of latex primer left over. I was wondering if I could paint over the top coat with this primer as a way of getting rid of this excess paint. I can't return this paint as I have already had this paint tinted to match the same color as the house (dark gray). Would this latex primer affect the top coat (also latex) in any way.
