That's a fabulous blue and white paint job! Didn't see that coming! I have one of these kits, and I've looked into it a few times, only to poke it back into the box. I have to say, I never had an idea that blue and white would look that good on it.
I looked at those, too. It appears that you need self adhesive sandpaper in whatever grit you want to use, trimmed to fit the stainless sticks. Advantages might be that they are fairly thin and flexible, more so than plastic or popsicle sticks.
