Review on 🔮 GPA14004 High-Grade Polishing Compound Solution by Danny Poulin

I bought this polish to repair a scratch on a tempered glass cover of one of my solar panels caused by the sharp edge of my wiper. Apparently the reason for repairing the scratch was not cosmetic. I was concerned that the scratch would cause stress concentration that could lead to a complete crack and many heating and cooling cycles over time. I was hoping that polishing the scratch would remove the residual stresses around the scratch and reduce stress concentration. The scratch was deep enough to easily scratch the nail. I polished it by hand. After the first 5 minutes of going through it (I guess I didn't time it. The scratch was about 4 inches long for reference) I couldn't see the scratch through the remaining paste so I cleaned and inspected it. That. After looking for a while I saw that it was barely visible so I downloaded a notepad and tried again. After another 5 minutes and cleaning again, I couldn't find the scratch anymore. It worked as advertised and I'm glad I bought it.
