Nope have not. Polywstch seems expensive for such a small tube. This one is in 250ml bottle. I use it for car rear lights and convertible top rear plastic window which turns it clear like new.

Hard to see how polywatch can surpass it. At most equal it as it leaves a perfectly clear and mirror smooth surface under loupe in 5 mins. I just use a thin dab about 2-3mm diameter. Feel running fingers over crystal is like new plexi, slick. Not like wax surface but slick like new plexi

I thought my monaco crystal was good but after using this the markers look like the glitter more. Gues because its more transparent even though it already looked like new before (but without that slick feel brand new plexi if you know what I mean)

Under "ingredients" it lists: mild soothing components, titanium compounds, minerals and auxillary agents.

Made in germany.

Btw i am not selling or manufacturing this product. Just a user.
