I'm nearing the end of giving my car a good cleaning session (started at 12)...

Just wiped over the glass with AG Fast Glass, glass came up fine but little water spots all over it.

So i went to the shed & pulled out AG Glass Polish, glass is now blindingly glossed but still, tons of water spots all over it.

I've tried putting pressure on it, but minimal to no effect.

Any secrets to getting water marks off?

And the windscreen has Aquapel on it, im not sure if i should be using fast glass / polish on it?

AG Glass Polish should help. I found Halfords intensive glass cutter helped a lot with my windscreen problems, its quite aggressive and will strip off most crap including any ruminants of Aquapel/RainX.

Have you tried "claying" the screen?

Not yet, been to 2 halfords & none of them have clay

Really needs to be sorted though, my windows are all crystal clear but look as if they have a severe case of acne.

is the ag glass polish any good and worth it?i was thinking of buying some to go over the fast glass.

Glass polish is abrasive so it will remove the aquapel, fast glass is just a glass cleaner that will have little effect on the glass sealant.

To remove water spots after you have tried glass polish I would reccomend claying the glass then using glass polish on it again.

try spirit vinegar
