Are you a professional spray painter, or are you paying someone to do it ? If the answer is no to both questions then don't pay the money. I believe that the product is not sold officially to the retail market.
Worth looking at the Epifanes paint range from Marineware for some good allround two pack.
Sorry if I have missed a thread on this elsewhere on the forum.
I have used Awlgrip, a premium product without a doubt but not worth the outlay unless you have the experience and equipment to do the product justice.
