what is the box?? green?
weird, never seen green primer before... but maybe that's common lol...
how hard was it to put primer on mdf? did you have to use a ton? what color are you painting and what type of paint
think i should try primering my first box? haven't build it yet.
I think it'd be easier than carpet... but maybe carpeting a box isn't as hard as I'd think it would be...
