About time I posted my own evaluation of Red Volunteer .....
I acquired 2 fans of this cultivar in August 2015 which were potted up. In October 2015, they were transplanted into a new raised bed. I wasn't sure how much I would like this un-fancy bloomer, but sometimes one can underestimate the impact of a solid color bloomer with a bright yellow throat! It stands out in my garden. Maybe it's because I love the color red.
This year in May through June (2016) I had 2 scapes produce 8-10 buds on each. The scapes stood up above the foliage and handled the large blooms with ease even during inclement weather. I got 2 prolifs from the scapes which I rooted in water and have growing in pots to add to other areas of my yard.
I love this cultivar. It does indeed seem to be fairly rust resistant. The bloom color is beautiful if you like large, bright red flowers. A keeper for sure!

It does tend to slick a little bit in the heat:
