I'm an old fart so I still use dope. After you've taken off the sharp edges with the back of a #11 Xacto blade, take the shine off the tips with 400 grit. Thin the dope down about 30-50% with acetone in a small mixing cup. Dip the tips and wick off the excess on a paper towel. I prefer yellow, but it works best with a base coat of white. The nice thing about dope is that it doesn't add much weight and the acetone bonds well with the the plastic of the Master props.

There's no way to avoid chewing up the tips on a grass field, but dope and acetone can keep your tips in shape without having to rebalance the prop every week.
