I was at H.D. and noticed that they have melamine on MDF - black ones too. Problem is, I don't think paint sticks to it, so in that regard, might not be a good idea for a build?
I've heard that to paint anything that has melamine as a layer, it's almost impossible? I'm sure that's not the case...perhaps some sanding and some 'special' paint tailored to sticking to melamine would exist.
