Your Awning Will Shine Like New! Coverage: 3,000 to 5,000 sf per diluted gallon. When a stunning high gloss finish is what you need then Vinyl Polish is the product to use. Easy to apply; just spray on the awning and wipe off the residual. Vinyl Polish also creates a barrier between the environment and the awning surface which protects the awning from staining. Easy to remove with soap and water.
