I bought some of the above off fleabay this week. The instructions are all in German!! Does anyone know whether
you can use it on windscreens? or is it a definite no no!  2013 Dynamic Santorini black

You absolutly can. Apply with damp cloth let it dry buff off with clean dry cloth. Top tip on insides place an old towel over dash and door card edges before applying. The dust goes everywhere as you buff off and is a pig to get wet drips off dash.

Brilliant stuff but as above says, protect surfaces from the dust. FL2 TD4 GS 60 reg Facelift - so many issues
2019 DS. Terribly unreliable.
Sold DS for a 2021 Mitsubishi Outlander PHEV. Fingers crossed....
Sold Outlander for a 2014 SD4 SE Tech because I’m mental
Now greatly regret selling the Outlander. MPG of the FL2 is atrocious and so are the fuel bills. Fun though 😎
Couldn’t afford the fuel bills so back to an older Mitsubishi Outlander PHEV. Significantly better than I remembered it to be…

And always hoover last thing. Lol

Thanks for the answers chaps! Use it with confidence now!  2013 Dynamic Santorini black

I'm confused here, with both the OP's question and some of the answers given. AG Fast Glass is a trigger spray, which simply wipes off with a Microfibre (the clue is in the name) and it can also be safely used on all internal plastics and dash trims. Are you all getting confused with AG Glass Polish (formerly branded Glass Cleaner), which is a deep cleansing mildly abrasive white liquid, with a texture like their SRP? That is the product that tends to cause dusting, as it needs to dry on before buffing, not Fast Glass.

Either way, as a word of warning, if you have film tints on your windows, ie NOT factory privacy glass, DO NOT apply either product to the insides - it will wreck the applied film, as its solvent based. Foraging near Gaydon....

I don't recall it ever being in a spray but the name Fast Glass is the one I used. Unless they have changed it... FL2 TD4 GS 60 reg Facelift - so many issues

Not the stuff I've used. Mine was as you described, the white cream. Maybe I've seen the name elsewhere and call it that. Thinking about it I've always questioned why they called it Fast due to the time taken to get rid of the dust. FL2 TD4 GS 60 reg Facelift - so many issues
