Don't forget weight... coatings could easily add a lot of weight to the balloon and bring the float altitude lower. And may only be partially effective anyway. An alternative solution is minimise the weight and get as high up as possible, over about 10km or so there are very few clouds to get in the way.?

A water repellent is something that was thought of but never tried.I was thinking a product used for aircraft and automobiles I have used on my windshield once when my wipers failed years ago.I think it was called rain-x or liquid glass? Have to google those and see if they still exist. I know it worked great in a downpour while driving using no wipers :) The only worry is if these products will deteriorate the balloon films. Another spray is for cooking called PAM for anti sticking.Maybe fill a balloon with gas and try these to see if they hold up on the ground.
