so its been bugging me that my hood has been really dirty. no matter how many times i washed the car it was always dirty. my car is white and the hood is always off-white. i finally got around to buying the clay bar thinking it would salve my problems but it didnt. see it did work in making the surface nice and smooth but my hood is still looking dirty. is there any way i can clean it? i think its all the old motor oil and such when i working on the car.

i will post pictures up and show you how it looks.

would buffing it work? or would i need a repaint?

Buffing wont do crap for you. You need a polish that can get that discoloration off of the hood for you. If your doing it by hand it may take a while and quite a bit of elbow grease. By machine it should be no problem. You may be able to use a paint cleaner but I don't know if that'll be abrasive enough.

try a good rubbing compound (3m makes some good stuff) and a polish as recommended by audi90. use lots of elbow grease with the rubbing compound. can you get some good pictures of the hood for us? it's possible your clear coat is fubared.

AHHHHHHHHH!! so actually i tried a whole bunch of products, but not the rubbing compound. actually i gave up on trying to clean it and applied wax to it. it may not be white but its coated. all that working made me forget to take pictures. i will tomorrow in the sunlight. sorry about that guys!!

Try the rubbing compound. If that doesn't work, wet sand the whole thing with 1500 grit sandpaper followed by 2000 grit, then use 3M rubbing compound.

I used the above technique to bring back the shine to parts I got of a 1990 red (half of it looked pink) Celica at junkyard that was badly oxidized.

With your second picture it actually looks like the hood is oxidized. Gonna need some kind of compound/polish to get that hood fixed.

how would i apply the compound? is it just using a terry cloth and do circles?

use an applicator pad and do small, medium pressure circles.

I would highly advise against using brake cleaner on any painted surface. Even if it would work there are plenty safer ways to fix that. If you check out autopia-carcare.com they have foam wax applicators that are dual sided and work great for both polishing and finishing by hand.
