Purchased a 6 pack of pints for a project that I thought was very rusty. Turned what I thought was rust is faded red paint and this is not the correct primer for that. This stuff needs rust to turn black and I had to sand a lot off that did not turn black.
Have 4 unused pints for sale, buy one or buy more.
Square foot coverage for the pint liquid is larger than the normal spray can and had no overspray.
Call John to make some of this yours for your really rusty project.
