Depending on how many coats you want and how thick you want it, but one quart will coat the entire frame and you will still have enough left over after one coat, that stuff goes a long ways. Make sure you either sandblast the frame or wire wheel/grind it good, if it doesn't have a good surface, it will peel off. And make sure you wear gloves, it takes days to get it off your hands

If I recall correctly, POR15 isn't UV stable so it only works on parts that never see the light of day.

Many in the dune buggy hobby use DuPont Imron and similar high durability paints instead of POR15 - just as tough and UV doesn't bother it.

This is correct. If one is to apply POR-15 to frame, it will need a coat of paint afterwards to protect the POR-15 & last-

What about using POR-15 on the frame then using that spray on rubberized undercoating? Would there be any problems with that?

I don't think there would be any problem, I'd guess the undercoating would stick to the POR-15.

The issue I would have is that the undercoating is eventually going to get damaged and need touching up. Making it look good won't be easy. Touching up paint is relatively easy (this is also why I don't care for spray on bed liners).

If the undercarriage painting is for appearance as much as protection then I'd use a durable paint like DuPont Imron - tough, shiny, easy enough to repair if damaged. If the point is to simply protect the undercarriage and no one is actually going to be looking at it then POR-15 and the rubberized undercoating would probably work very well and if an area is damaged it wouldn't matter - just dab some more on, if it doesn't quite match no one will care as it's not being looked at anyway.
