Frequently Asked Questions

AI
Silicone sealants are flexible, waterproof adhesives ideal for bonding glass to metal, such as windshields. Butyl tape is a pre-formed, non-curing rubber strip used for creating watertight seals around headlights, trim, and windows without the mess of liquid sealants.
No. Ceramic coatings are hydrophobic sprays that protect glass from water spots and UV damage but do not provide structural adhesion or waterproof sealing for gaps and leaks. They should be used alongside, not instead of, proper sealants.
For motorcycles, a flexible RTV silicone or a high-quality butyl tape is recommended. These materials withstand vibration and temperature changes better than rigid adhesives, preventing leaks and cracks caused by road stress.
