I think those products should work fine. But, be aware of a couple of things. It's REALLY glossy and REALLY white and as I recall, HD won't tint it.
Sherwin Williams has a similar product called All Surface Enamel which comes in Satin and they will tint it any color you want.
On a different note, I'm guessing from the picture that your stand is for something like a 55 gallon aquarium? Are you comfortable with the 1x4 frame holding 400+ pounds of water?
