Krylon Gallery Series UV-Resistant Clear Gloss
The Krylon Gallery Series UV-Resistant Clear Gloss provides a transparent, durable finish that protects plastics from UV rays. It is designed to prevent yellowing and offers a permanent coating that dries to a high-gloss look. Best for art projects, display pieces, and clear coatings on decorative plastics. Caution: over-application can lead to runs or uneven gloss in tight spaces.
Krylon Gallery Series UV-Resistant Matte
This matte spray offers UV protection with a non-glossy finish, ideal for crafts that require a subdued look on plastics. It resists yellowing and provides a durable surface suitable for items that should not appear shiny. Better for understated projects where glare must be minimized. Caution: matte finishes can sometimes appear uneven on highly textured plastics if not applied in thin, even coats.
Krylon COLORmaxx Crystal Clear Gloss
The COLORmaxx Gloss Crystal Clear provides a bright, glassy finish with UV protection for indoor and outdoor plastic surfaces. It offers a robust coat that resists fading and helps maintain the appearance of clear plastics over time. Caution: gloss finishes may highlight surface imperfections on rough plastics; prep may be necessary for best results.
Ultimate UV Protection Spray (Marinamax)
Marinamax offers a professional-grade UV protectant intended for outdoor plastics, vinyl, and rubber. It claims a stronger formula that shields against fading and cracking while forming an invisible barrier that also resists dirt and stains. Best for items exposed to sun and weather. Caution: labeled as a protective spray rather than a color coat; it may be used as a top layer rather than a color finish.
303 Aerospace Protectant Spray
303 Aerospace Protectant is a versatile UV protection spray designed for outdoor vinyl, plastic, and rubber surfaces. It offers a matte finish and reduces fading and cracking while repelling dirt. Best for outdoor gear, boat interiors, and RV surfaces. Caution: matte finish may feel slightly dry to some users depending on surface porosity.
