Can you see the rear subframe on a curvy? If not all your re-painting it for is to prevent corrosion and prolong the life of the subframe. Personally I'd just buy a tin of gloss finish black metal paint for not much more than a fiver. You get metal paints now that don't need any primer and contain rust inhibitors in the paint, so you just rub it back, clean it up with spirit and then paint it.

Or I've heard that if you use an enamel paint and apply it to a heated metal surface it will last as long as powercoating.

My XT600 you can see the subframe, but I'm still just going to paint it myself, as to see it you have to get your head down by the back wheel and look up, so nobody but me ever will.
