Can GP-PRO Glass Polishing Compound Damage My Glass?

No, when used correctly, GP-PRO Glass Polishing Compound is safe for all glass types. However, because of its higher cutting power, it should be used with the correct polishing technique to avoid over-polishing or uneven results.

Ottimo prodotto

Prodotto davvero utile. Trasformato un vetro opacizzato e graffiato in un vetro con una nuova vita. Rimasti solo o graffi piu profondi ma il risultato è davvero ottimo. Pubblico le foto del prima e del dopo.

Works well with a polisher...

11 years of buildup on auto glass. 90% removed and fine abrasives left no polisher marks. Dries quickly so I sprayed pad while polishing.

My car is 7 years old and it has never been in the garage. It also went through hot summer and harsh winter. The windshield was not in good shape. And it is getting worse and become dangerous in rainy day especially in the night. The micro scratches on the glass diffuse the light and blur the view. I search online and find this. After some elbow grease, the result is quite good. See the picture, I washed it and didn't dry. There were streaks left over.

¡¡¡Espectacular !!!

Lo mejor que he probado en los cristales del coche, es una pasada, no encontraba nada que quitara ese blanquecino del cristal que tantos años al sol y lluvia habían dejado las ventanillas muy opacas. Con un taladro de batería, una esponja semi rígida y paciencia lo he conseguido. No están al 100x100, pero diría que un 95%, aún tendré que darle un repaso más a fondo más adelante, pero de momento los dejo así.

Purchased this product to clean a ground light which had corroded and discoloured.Following the instructions via the QR link the results are amazing. I used a handheld polisher to apply.

Works great!

The window was a 30+ Y/O Viking that was original to the house. Many years of lawn sprinklers had left the glass very spotted with calcium and silica. Wasn't sure if this would work, or if I had the right equipment to apply it. Didn't have a orbital polisher but I did have a small orbital sander, and I found some 2000 grit sanding disks in my stash, which I though should work. I used small dabs of the polishing compound, the 2000 grit disks, squirted water on the glass as I polished. The whole process was much easier than I thought it would be and it turned out really great!

Mira que gastamos dinero en tonterías la gran mayoría de las veces pero ahora este producto me ha sorprendido que me alegro el día de lo feliz que me hizo. Los cristales de mi cacahuete no se veían nada de lo rayados que estaban hasta el punto que quise llamar al seguro y dar parte .me decidí probar con este producto y por arte de magia casi en 5 minutos los cristales nuevos. Yo lo hice con el taladro con un acople de esponja para pulir y poco producto luego lo moje con limpiacristales le seguí dando un poco luego lo limpie bien y ahí están como nuevo . Un 10

Funciona pero depende...

Es un buen producto, pero para cristales de relojes (yo lo utilize solo para eso) cuesta mucha fatiga!! Hay que utilizar un fieltro duro y muchas revoluciónes al taladro o dremel que sea. Y adivinar la mezcla entre agua y polish. Me costó tres horas de trabajo para un arañazo que no era bastante superficial.Al final el resultado ha sido muy bueno, pero no se puede gastar asi mucho tiempo para un micro arañazo. Para mi la pasta debería ser no una, si no dos. Una mas abrasiva y la otra para la pasada final. Pero es una mia suposición, no se mucho acerca de los vidrios. Pero conozco muy bien la mecánica de precisión, porque soy tornero. Yo creo que si una persona no tiene ninguna experiencia manual de este tipo se va a desanimar.. porqué no le va a salir bien el trabajo.

Polish for surface scratches only

This worked really great on the surface scratches. The deeper dog nail scratches are still there, but less a bit smoother.The after picture on the right shows they are less noticeable.I used my drill and a buffing attachment.I did 4 application/buffing rounds.

Took scratches out of an amethyst stone!

Wow, I'm so pleasantly surprised that this worked!! I had been setting an amethyst cabochon into a sterling ring shank I made & scuffed the sides of the stone while doing so. Due to the expense & it was already set, I didn't want to ruin the ring by taking it out or starting over!I bought this cuz I had heard that cerium oxide may work to take scratches out on some gems with a flex shaft. I went over it 3x with the cerium oxide on a hard wool felt wheel. Then I went over it once more with this on a soft wool felt wheel. After cleaning it up, I couldn't believe there was ever a scuff present! Good as new, and it didn't affect the silver either!! I highly recommend this stuff. I'm glad to have it around in case I ever scuff another stone. Great product!I forgot to take before pics, but I will try to attach a picture of the unblemished amethyst after polishing with the cerium oxide.

Composto efficace per graffi leggeri e opacità, con buona resa professionale; richiede però pazienza e non funziona su graffi profondi.

Absolutley greate, I had problem with my windscreen in my car, no matter what I use before to clean glass, what kind of wipers I use and what kind of fluid my wipers wasnt enough to clean it, always dirty, always wet and watter didnt go down. After I use Glass Polish Pro everything change. Watter drops go down immediately, one mowe of my wipers clean my windscreen almost perfectly.It was very easy to use, all tiny scratch are gone. Finish was simple, just use watter to remove it and leave clean surface. Product comes in 50ml and 100ml bottle, both are cheap, but one bottle of 50ml is not enough for all windows, better take 100mm.
