It rather depends on the type of water mark you have.

One type is just a light crystalline deposit caused by hard water drying on the car in the sun for a short while. The second being those which have been left rather longer on a hotter panel causing the crystals to sink into the paint slightly leaving an imprint or 'etching' in the paint. And thirdly, those where the paint has become porous for some reason and caused a discolouration due to water ingress causing the paint to lift slightly.

Type 1 - Normally a mild acid will remove the deposits. Even a glass cleaner or in some cases a quick detailer if caught quickly enough will remove them.
Type 2 - You will need to get in to machine polishing or possibly wet-sanding to remove any etching in the paint in order to bring the level of the surrounding area down to the bottom of the damage.
Type 3 - Oh dear. Where heat can temporarily remove the issue it really is time for a respray or more in depth work to cure.

Hope that helps!

That's a coincidence. I was about to ask that question. From the answers given mine falls within the second category. Only worry I have with machine polishing is that it I had this done a few years ago and not sure how much depth of paint is left. Did try using T cut and although this did improve it somewhat the marks are still there.

Careful with the T-Cut it can be quite harsh. I will be bringing my ultrasonic paint thickness gauge to Curborough again this year if you'd like to find me on the Saturday - that way we can see exactly what paint you have available to play with.

Thanks for the information/advice I am going to try and attempt a small area today using my rotary buffer and some none abrasive polish and glass cleaner.

I have a different type of water mark on the SS1 which is - I am embarrassed to say :oops: - entirely of my own making. After a long period of neglect, we rushed to get it ready for drive-it day. This included a quick rub over with Farecla G3 to restore the flat paint finish. Obviously we planned to protect it with a coat of polish later :roll: . Shortly after I lost storage and left it at the bottom of the garden covered in a tarpaulin - temporarily. After all - it was June. There wouldn't be much rain anyway :roll: . After a couple of weeks of pretty much continuous rain there was some serious patchiness on the bonnet so I just erected the tent over it, replaced the tarpaulin with what remains of the car cover (the mice have taken their toll) and left it 'out of mind' for a while. I'm hoping a bit more G3 and some polish will bring it back to some reasonable finish (it will never be more than acceptable due to general age). Hope I am correct! Wonder what the best polish is :?:

I think the protective cover I had over it didn't help even though it is a breathable type, it is a temporary measure until my carport is built however it seems the water marks
are gradually disappearing since I have left the cover off so hopefully a good polish will sort it :)

Rule no.1 of a Scimitar ownership - never fit a cover if it's outside..

Hrmmm not strictly true on the cover issue.I'v had a 6a covered continuously for 14 months outside.was resprayed by mike 18 months ago ,so new types of paint seem more forgiving...i'm not recommending anyone dose it before anyone starts
