Sorry I am late to the party Ron, I just found your email looking for my opinion.
Paint is absolutely the way to go. Subframes are never perfect and powder coating amplifies the imperfections. With paint you get a chance to prime, even fill if needed, smooth and color. Also mentioned is the touch up ability of paint vs powder coat.
It is funny because everyday I get someone wanting to powder coat their rear end, subframe, to protect it because they do not think paint is good enough.
Then I ask them, "What do you think takes more abuse? You rear end under you car? Or the lower quarter panels that are having stones thrown at them by the tires?
Paint works on the lower quarters, it will work on your rear.
I think a lot of the illusion comes from people comparing the condition of their original rear / frame they removed. The original cars were rusty before they came off the truck. I remember looking at new cars on car carriers and seeing all orange surface rust. Those factory rears and frames got washed with a paint GM used to sell that said on the car you could paint your rubber floor mats with it to! good stuff, LOL!
So we paint it just like it is the outer body. Sandbalst it to bare metal, epoxy primer and urethane top coat.
