Ideal temps for application range from 30F - 95F, however HyperDip is sensitive to humidity. Humidity levels at or below 50% are ideal. HyperDip® protects your wheels from acids, abrasion, corrosion, impact, salts, moisture and weathering. It remains flexible, stretchy and will not crack, or become brittle in extreme temperatures when applied correctly.HyperDip is not compatible with traditional Plasti Dip, so please do not combine or stack the two products.Test all applications in a small inconspicuous area to make sure it will meet your expectations and is suitable for each unique surface. Although HyperDip has proven to be safe and predictable, every surface is unique and it's impossible to predict how each surface will react.
