A number of flyers here in the Northwest have been real happy using Rain X. Yes it’s the Rain X that people use on their windshields of their cars.
Simply take a piece of small toweling, may be 4 in.², soak the towel in Rain X and then put it in a small zip up plastic baggie. At the field after you have set up your lines, simply run the damp towel down the lines, then at the end of your flights before you wrap the lines up wipe them down one more time with the Rain X. Now your lines will be both waterproof and lubed.
