I had a minor scrape on my 4wd a few years ago and put some fish oil on it. It dribbled down and I didn't think anything of it. I came to waxing the car a few weeks ago and tried to remove the excess fish oil, but nothing seems to get it off. I've tried automotive thinners, petrol, metho, but it just doesn't budge. Anyone got any other ideas.

Yes, been there done that!
Have you tried wax-and-grease remover (AKA "Prepsol") or Shellite™️ (naphtha)?
Yeah far as I'm aware mechanical removal of the surface affected is the only way - wire wheel or sander etc. Gets into spaces way too small for other solvents.

Hammer & Cold Chisel ? ???
You could try Oompf spray on product (goo and stain remover) available from hardware store. You may have to apply heat with hair drier as indicated by Sportiva, if hard and won't shift on its own.

I believe sharks like fish !!!
no seriously brake cleaner BUT be warned if its acrylic paint it will take it off
the first thing i would do is use fresh fish oil on it it will absorb some of the moisture and shou;d be able to get it off
apply to a small rag tape it on and leave overnight
