Meaning and boundaries
Unplanned field removal is not the same as controlled factory edge deletion and does not restore the original coated product by polishing the exposed glass.
Why it matters in glass restoration
Removal can change color, reflectance, transmittance, emissivity, solar performance, appearance uniformity, and warranty status.
