Found an old bottle of this in my cleaning cabinet this afternoon....I haven't used it for about 6 years, since I discovered the non-silicone Autoglym equivalent.

Anyway, I had about half a bottle in there, and I hate waste, so decided to do a little experiment. I applied it to the D Pillars, side moulding strips and rear lamp guards, as they were looking somewhat discoloured and lightly scratched...left it for five minutes, and then lightly finished with a Microfibre cloth in straight lines...the results were astonishing. Almost like new, and as much as it pains me to say it, it knocks the Autoglym Bumper Gel into a cocked hat....Never thought that I would say that!

Recommended if your dark plastics are looking tired and need a spruce up..... Foraging near Gaydon....

Turtle Wax is good, I use very cheap Zipwax wash and it cleans well.

Couldn't agree more Badger. Their speed wax is great too.
