Could this be used on prescription eye glasses with a glass finish?

I haven't used this on actual glass - particularly prescription glasses. I have only used it on poly watch crystals and the occasional poly CD/DVD. Given that the product specifically says it is for use on poly surfaces, and it's action is to slightly abrade and then fill the scratches with polymer I would be very cautious using it on glass, especially glass you have to see through. Given my experience and the instructions that came with the product, I would strongly discourage someone from trying this out on eyeglasses.

Does it work with hairline cracks?

This product will not repair cracked crystals, hairline or otherwise. It works on scratches only, provided they are not too deep.

Can this be used on phone screen?

This product is for plastic watch crystals. If you have a touchscreen phone it is most likely glass and there is a separate glass product that should work

What is the difference between the tubes that say "Plastic" and "Polish" on the ends?

Never even noticed that. I have 2 tubes, one has the "Poly" in fat letters and the other thin, both have "Polish" on tube. No difference in the compound what so ever. I would just say its a printing difference on tube, compound itself is probably no different than the other.

positiv überrascht

Hatte durch einen Sturz mit dem Fahrrad zwei tiefe Kratzer in dem Hesalitglas meiner Uhr .Einen guten Tropfen Polywatch aufgetragen und zuerst parallel mit den Kratzer und mit Druck gearbeitet. Danach immer wieder abwechselnd mit kreisenden Bewegungen feste poliert. Ich muss sagen mit solch einem perfekten Ergebnis hatte ich nicht gerechnet. Das Glas sieht fast wie neu aus .Natürlich kann man bei entsprechendem Lichteinfall noch sehr geringe Polierspuren erkennen, aber nur wenn man sehr genau hinschaut .Kann dieses Produkt uneingeschränkt empfehlen

Not in original box

Does not come in original packaging. Only the tube. The full package box should contact the polishing cloth.
