Can I coat my sails myself with Sail & Spinnaker Coating?
You can coat sails yourself with Ultramar Sail & Spinnaker Coating.
Lay your tarp down on a clean surface. For example, a foil from the hardware store.
Then treat 1 side with a paint roller or spray and let it dry.
Then turn the sail over and treat the other side.
Optionally, you can leave the sail on the boat. For example, you can always hoist, treat, hoist, treat, etc. a mainsail.
