I am trying to figure out the right chemical balance to POR15 primer(reducer, hardener, primer). Im going to be spraying 2 doors, 2 fenders and a dash. any idea how much i need to mix up?
thanks
Robert

i wasn't aware that POR15 made a primer that required the use of either reducer or hardner// go to thier web site for tech advise they're very good with directions on how to use thier product
