Sorry, meant Exit Long day.

Yes I did paint it on a horizontal surface instead of vertical as it would normally sit. I think it is better to start this way to get the feel of the roller and fine tune the mixture of the mineral spirits. I also found that I always had to error on the side of more mineral spirits.

Color is Safety Red, Rustoleum Professional Series, Duplicolor 100% Mineral Spirits (NOT low oder) that I got from Advance Auto, and I am using a spray can of Safety Red to get into areas that would be too hard with a roller.
