YOU DON'T HAVE TO REPLACE YOUR SCRATCHED GLASS.
The scratch depth is measured to determine the severity of the scratch and the expected outcome result. The scratch length is measured to determine the material use and the time of the job.
LIGHT The scratch is 1/1000" deep or less. The scratch will appear light white in color. It can be restored with no distortion and minimal abrasive steps.
MEDIUM The scratch is over 1/1000". The scratch appears distinctly white in color. It can be removed with multiple steps with minimal to no distortion in the glass.
DEEP The scratch is up to 3/1000" deep. The scratch is white in color and can be scalloped on the edges with glass missing along the scratch edge. It requires multiple abrasive and polish steps to remove the scratch and restore clarity. Slight distortion may occur from the repair.
SEVERE The scratch is deeper than 3/1000" and visible distortion will occur by removing the glass to the bottom of the scratch.
EVALUATE DEPTH & LENGTH
The scratch depth is measured to determine the abrasive steps that are needed and to gauge the blending area to avoid distortion. The scratch length is measured to determine the time spent using each abrasive step and estimate the total time of the job. The scratch depth can be measured using a Digital Micrometer and the thickness of the glass measured throughout the process using an Ultrasonic Instrument.
The initial scratch is removed using the most robust abrasives that remove the surrounding glass in increments of less than 1/10,000th of an inch per application. When the scratch is completely removed, the glass will be opaque and/or white from the aggressive abrasion.
