its easy, mix the hardener with the paint, roll it on, brush it on, whatever, let dry, sand, repeat.
keep this process up until you have the desired coverage. buy PLENTY THROW AWAY ROLLERs, PAINTBRUSHES, PLASTIC BOWLS, RUBBER LATEX GLOVES, AND SAND PAPER.
It is like working with fiberglass, just colored. It dries slower too.
