Will this yellowing come out of engine bay paint?

[kimokalihi]

This is the engine bay of my 91 Subaru Legacy SS. It's supposed to be pearl white. So is the exterior but I'll get to that in another thread when I get a chance to snap some pictures of the 23 year old paint and post them in another thread on the car when I'm ready to work on the outside.

I'm slowly getting the car ready for a car show in september so I've got some time but I'd like to know if you guys think this nasty yellow will come out of the paint of the engine bay and what the best approach to getting it looking as best as it will would be. I was thinking one of those powerball minis and maybe the cone shaped one for tight areas with a compound. I have M105, M205, Ultimate Compound and a bunch of other random compounds and polishes.

You can see both on the fender and the area between those two bolts the color difference of what it should look like and how it's somehow gotten yellow in a bad bad way. I think this is from repeated exposure to oil. At one point the engine blew up and covered most of the bay in oil while driving it home on 3 cylinders. But it was yellow before that as well.

I would try working that with a chemical polish. Something like Poorboy's Pro Polish or even a metal polish would chemically work at the contaminates in the paint and possibly bring the paint back to it's original color or closer to it. It's been my experience that chemical polishes work better at removing stains that abrasive compounds don't really do so well with removing.

Do you have any metal polish to try?

[BillE]

Just an idea, try a weak of bleach and water. Let is set a bit then agitate, rinse. Like I said, this just an idea. Oil staining is a bear to remove from clothes (read-white T-shirts), but sometimes adding bleach to the wash water can help.

What have you tried already?

You'd better be careful when going over whatever that sealer is in the corner. If it's soft you might pull the paint off of it.

I can't believe I myself am suggesting it, but since I just picked up on it, I will suggest claying it. Safest technique to start and see what happens. Maybe some Meg's moderate clay for some bite, or if you cannot get that, try the mild. At least this is what I would try. I, too, have a white car so I'm sure this will happen to me too. -Ed

Unless Subaru had a footprint where you live back in 1991...
Your vehicle was probably shipped across the open seas from its assembly plant.

Thanks guys! Its actually yellower in real life but I couldn't get my phone to accurately capture the nastiness. I soaked and scrubbed with meguairs apc+ before taking those pics so its in the surface pretty good.

That cosmonot sounds pretty promising. I think ill try that.

Its not that soft. Its factory stuff under the factory paint and its all over the bay on all the seems.

I do have a bottle of meguiars all metal polish.

Thanks for the remedy to the situation. My wife's Mini Cooper S has got cosmoline all over the hinges under the hood and door areas and APC would not work, going to give the prima a try.

[kimokalihi]

Alright funx725, I ordered the prima cosmonot product. Hoping it helps. What is cosmoline anyways?

[rcomito]

Cosmoline is a rust preventative. When I was in the army, it seems like everything was packed in it. It's a chore to clean off, but it does it's job well.

I see. No reason for it to be on the paint then and we don't get much rust in the PNW.

Cosmoline also protects from: Sea-Salt-Spray-Rusting-Conditions.
Where was your Subaru assembled/shipped-from?

Maybe Indiana?
