At one time, I was buying APC props in six pack bags..

We fly on grass, actually, a grass runway for full-scale. We cut the grass as often as we can, but it's still, well, more like straw than grass. It grows fast after a rainfall, so often, we get these long chutes of this straw like stuff that is almost as hard as wood, and is about a foot long. At times trainers can't take off. My pattern bird will pretty much chop thorugh that stuff, but it leaves the props green with stains, and takes paint right off. That mix of green from the grass and the red from the fuel (S&W 15% has a red die in the oil) makes for a pretty awful looking plane after a few flights.

So, I don't paint the props.
