I have completed the Kiwigrip job on Radiant, using the KG white paint tinted to Benjamin Moore "China White" (a warm light grey) by my local hardware store. Application was easy and the results are great!

KG recommended 2 gallons of paint, but I only used 1 gal. + one quart. Except for the bow, I opted for a less aggressive surface which used less paint. There is some difference to the texture from area to area, but it is acceptable.
Jamestown Distributors sells the "loopy, goopy" roller covers in 3" and a "3" roller handle which was 4", leading to build up on the ends of the roller and an inability to get close to the edge in places. A better option is to buy (2) 9" roller covers and cut them down with a saw (the cover is kind of brittle) and you will probably need a few 3"-ers, since they unravel before the job is done.
3M Special Adhesive Thinner is great for clean-up, even after the paint has dried.
