I was just reading one of my 4 OZ cans of POR 15 under application procedures it says{IF SURFACE HAS BEEN FRESHLY SANDBLASTED YOU CAN JUST BLOW OFF ANY LOOSE DUST OR DIRT THEN APPLY POR-15 DIRECTLY OVER SANDBLASTED AREA} WICH IS WHAT i did and I confirmed that with the folks at Por -15.I think they probaly have a great product and that I should have went ahead living in a high humidity area, went ahead and used the metal ready and I would have been fine. This mistake is going to set me way back on my project and cost more money.If I can give anyone any advice on this ,it would be to use the metal ready,reguardless.
