BOLL Anti-Gravel + Sprayable Sealant 2 in 1

Anti-gravel + Sprayable seam sealant 2in1 is a universal agent based on rubber and synthetic resins, which forms a flexible structural coating that protects bodywork components against mechanical damage and corrosion, while also acting as a sealing, anti-vibration, and sound-absorbing compound. Used to protect sills, bumpers, and spoilers from stone chips and weather conditions, it seals the joints between metal sheets and car body parts, creating the structure of the original spray sealant. It is resistant to water, oils, and salt. Once dry, it can be covered with all paint systems.

Method of Use

Thoroughly clean, de-grease and dry the areas to be coated. Protect adjacent surfaces using suitable masking paper.
