[AT] Tractor painting--hardner in primer

[Terry Welch]

There are some primers that have a harder for them. Not paint hardner, but special just for that product. It will make the primer hard and if left long enough it will be very difficult to sand.The purpose of this type of primed is to close all the pores and not let moisture in. Dupont used to make one for equipment painting, you had a given time or to had to recoat as it very hard.
