Glass coating is few micron ultra thin layer of protection, an affordable protection option against mild environmental fallout, dust/debris and oxidization. PPF is a tangible and solid form of protection against scratches, stone chip, environmental fallout and oxidization. PPF is so robust as its thickness is considerably 200% to 400% thicker than the original clear coat. These two options only require a weekly car wash and spray on sealant minus out the polishing and waxing to stay vibrant.
