Does MDF need to be painted?

I have some MDF subwoofers that are not painted. Can I just cover them with something instead of going through the hassle of painting them?

I live in Arizona and it is hot and dry here, but ocassionally there is some humidity. As for sealing with polyurethane sealant or something like that, do I need to do the inside and outside (in other words dis-assemble the unit) or can I just do the outside?

Just imagine if they're painted a high-gloss black... mmmm... Dewald I once had a set of floorstanders from MFD sprayed with BMW's "Mauritius Blue" by a paint-shoppe - looked mighty fine I say!
