thank you finaly something that make sense to me, personaly i dont care much for the omni brand epoxy primer every time ive sprayed it it seemed to always have a problem with something, temp wasent perfect, or the cat. was old, not enough reducer to spray right when mixed by the spec sheet. inproper air psi settings stated on the spec sheet. personaly i wont use it again on another high end job, ill use just regular base coat it serves as the same thing ans theres less problems. thnks for the advice
