Black tyre marks

[pandos]

Anyone with experience of getting these off a white fiberglass hull.

I haven't tried yet but boat is 4 hours drive away and time before saying is limited.

They look pretty bad and have been on there for a few years I suspect...

Regards.

You can try a Car Shop that sells the spray on Tar Remover .... but you really are going to have a job on ... its hard to remove those marks.

With real stubborn marks - I often resort to Oven Cleaner .....

I usually start with basic organic solvents like white spirit or a strong gelcoat cleaner. I find that most marks actually just come off with a wax or wax polish and a good rub.

My go to for this type of stubborn dirt is a Magic Sponge.

Magic Sponge

use with one of the proprietary 'black stain remover' of choice.

Another vote for Magic Eraser

You could try olive oil, it even removes that annoying adhesive left when removing labels.

Magic eraser are really abrasive - the scratches are just really small. Better to use a polishing compound imo.

Yes I had just googled these yokes.

I think wd40 may be a starting point maybe white spirits and acetone, if all comes to all cutting compound or very fine wet and dry..paper..1600ish..

Thanks all...

I would go acetone on a rag. ol'will

Mix it all together on a rag and if it doesn't spontaneously combust you are quids in!

Asking this question before Nanny State took hold, the answer would have been “petrol on a rag”

Even if you clean off the tyre rubber marks, I suspect the gel coat will have been abraded with grit on the tyre. You will need to compound the gel coat back to a shine and the use at least 3 coats of a high quality polish that includes UV protection.

Magic eraser. Does it easy.

I was going to include acetone but I believe that it can soften gelcoat and needs to be used carefully. The vapour is nasty and not good in a confined space.

In my past life tinkering with fibreglass kitcars, I used products from this lot and they were very good. Marine | Farécla

Don't worry no nanny State where the boat is...that may be the easiest option be cause I can't find the half gallon of acetone. (But it could be at the boat)
It's the outside of the hull so pretty well ventilated.

Thanks to all others for helpful suggestions...

Audi driver, was it?

Xylene. Acetone is not really a petroleum/rubber solvent; too polar and it dries too fast. Xylene is the main ingredient in most tar removers or other aromatic (xylene is an aromatic solvent--it is a solvent class, not a reference to the smell) solvents. Give it some soak time ... the thicker the layers the more time.

Been there, done that. Not magic eraser either, except perhaps for the last bit.
