What is the best way to paint a large piece of glass (4ft x 6ft) opaque black? I was thinking about using PlastiDip, any opinions?
I considered film, but it's hard to find decent priced film that is 4ft wide, and I don't want to deal with seams.
I am turning it into a black dry erase board that will hang on my wall, so this will be the back of the glass. I am willing to put the time needed into it, to make it look decent. The size of the glass makes it a little awkward to work with.

Most high quality enamel and acrylic spray paints will stick relatively well to glass; you will still need to take care not to scratch it.
I would clean the glass well with denatured alcohol to remove all traces of oil, dirt, etc. and spray at least 3 coats (following paint manufacturers instructions). Let it cure for a long time prior to manipulation, dry to the touch is not the same as cured. Unless you have some mad skill, I don't think a brush-on finish could match the "near perfect" finish of spray. Practice on scrap pieces to get comfortable with your paint brand, it's worth the money for an extra can for this, if you need it as nice as you state in your comment.
Consider a thin cardboard pad somehow attached to the back to protect the paint from being rubbed or scratched off, whatever frame ideas you have could probably accommodate that.
