What is the difference between glaze sealing and crystal coating?
2 Answers
The differences between glaze sealing and crystal coating lie in their composition and function. Composition difference: The essence of glaze sealing is similar to waxing. 'Glaze' is extracted from petroleum and mixed with some auxiliary materials. After cleaning the car surface, the 'glaze' is vibrated onto it, allowing full penetration between the glaze and the paint surface. Crystal coating uses inorganic substances like silicon dioxide, forming a solid crystalline isolation layer on the surface through molecular polymerization. This isolation layer has functions such as UV resistance, oil resistance, low surface energy, and hydrophobicity, thereby protecting the paint surface. Function difference: Glaze sealing serves to block UV rays, resist oxidation, withstand high temperatures and acid rain, prevent minor scratches, enhance the original paint's gloss and hardness, prolong the paint's lifespan, and slow down browning. Crystal coating is currently the most advanced car paint protection solution, offering advantages like corrosion resistance, scratch prevention, no cracking, and easy cleaning.
Having maintained my car for over a decade, I've found that the main differences between glaze sealing and ceramic coating lie in their composition and effectiveness. Glaze sealing involves applying a wax-based or polymer coating to the car's paint surface to enhance gloss and protection, but it lacks durability. I typically need to reapply it every three to six months, and it's relatively inexpensive, costing just a few hundred yuan per session. In contrast, ceramic coating is far superior. It utilizes advanced nano-ceramic materials that form a hard protective layer after application, offering scratch resistance and UV protection. My own car has been coated for over two years, and water beads still slide right off, making maintenance much simpler. Additionally, from an environmental perspective, glaze sealing may release more volatile chemicals during application, while ceramic coating is more eco-friendly. In terms of cost, glaze sealing is cheaper to start with, whereas ceramic coating requires an initial investment of two to three thousand yuan but proves more cost-effective in the long run. I recommend ceramic coating for new cars and glaze sealing as a temporary maintenance solution for older vehicles.
