Hi all
I have paintwork damage near my fuel cap obviously due to fuel. I have attached a pic and thats after a wash.
Whats the best way to remove or at least improve the appearance? I have tried T-cut but didnt really make any improvement (mind you i probably didnt try hard enough)
I think its just the clear coat thats come off so could i rub some on ? (Dont want to apray)
All suggestions will be greatly appreciated. Thanks

t cut isnt great at that sort of thing, you need a cutting compound polish like g7 etc, just go easy, then protect with a proper polish, and no you cant re apply clear coat with out spraying

As above you need proper cutting compound and seal it with wax afterwards.

Maybe pop to Halfords and get some Meguiars Ultimate compound.It’s probably harsh enough to remove that but not harsh enough to leave abrasive marks like some heavy cutting compounds can. It’s safe enough to do the whole car to freshen up the paintwork too. It’s about £13. Buy a couple of hand held micro fibre applicator pads too they will help to bring up that dulled paint. If you were in my area ( Staffs) I’d use my dual action polisher on it for you but have a go yourself you should sort it.

Don't use G7 or t-cut.
Use a compound made for 2k paint,G3 will do but ideally it wants machine polishing rather than doing by hand

Thankyou all. I'll try G3 and then seperate wax. Im a bit of novice but whats the opinion of you good people g3 or g7?
For machine polishing can i use polishing wheel attached to my (not so brilliant) drill?

Any chance it’s had a crash repair in the past? That looks exceptionally bad really. It’s like someone’s doused the thing in brake fluid.

The rear 3/4 panel doesn’t look that great at all. Not much shine to it.

Factory paint shouldn't really be damaged by fuel spillage. My race car has single stage cellulose and that very much is affected by fuel and it looks exactly like that

Today I eeded to get some rubbing scratches out of a car I'm selling. I bought some G3 from Halfords, mainly because all the T-Cut was colour specific, and I wanted a jack of all trades. I was blown away by the results, and highly recommend it. I bought the two-pack applicator too.

Problem is i rarely wash it and i dont fill the tank... only ever half fill it... so the amount of diesel splashes and the lack of washing may have done it! 🤣

It won’t splash out of a modern BMW. There’s an anti siphon flap down the filler neck.

Yes i know, its not that it splashes out of the tank, its the fuel that sometimes drops out of the filler hose as i remove it from the tank. I should shake it about abit i reckon! 🤣👍

It looks to me like a quick blow over to hide a scuffed arch.
Is there any sign of any masking off inside the fuel door aperture?
You could do with figuring out what you’re dealing with before going at it with any vigour.

Like i mentioned earlier ive had the ca mr fir about 7 years and its only just started appearing about a year ago. Ive just assumed its diesel because i do tend to get drops on the paintwork in that same area

When viewing the photo in Thumbsnap (enlarged) it looks like the panel has been repainted - dust nib on the left next to the halo of light and is that rust on the arch edge where it meets the bumper corner?

Worth 5mins of your time and some polish to see if the area can be improved but I expect that'll need repainting by a bodyshop.

Cheers.
