Color Match Touch Up Spray Can Paint For 2017 - 2019 Mercedes - Benz GLS450 GLS550 Brush Touch Up Spray Can Paint Please order based on color code only. Color names change between models or years of manufacturing. What is the difference between 1K and 2K Clear Coat? 2K (Urethane) clear coat is similar to factory clear. It has hardener (mixed by pressing on the mixing valve at the bottom of the can). Hardener increases gloss and resistance to UV, scratching and chipping. After hardener is mixed with clear coat, it must be sprayed within 6 hours. 1K (Acrylic) clear coat is a single component clear. It has no time restrictions, but has less gloss and less resistance to UV, scratching and chipping. If using around a gas tank, acrylic clear coat is not recommended. Recommendations: 1. Always test spray base coat before application. If color does not match, contact us via Ebay messaging system. 2. Primer, Base Coat and Clear Coat flow will change depending on the temperature. Lower temperatures will reduce drying speed, which may cause "runs". Before applying to the vehicle, test spray using spraying card (included in every order) to determine drying speed. Warranty We warranty all products for 60 days. If there is an issue with color or any other component in the kit, contact us via Ebay messaging.
