Surface rust Valley Pan

[Dennis H]

Trying to clean things up a bit underhood. New wires and going with stock orange valve covers. Noticed new surface rust. Should have painted it orange before install of the efi. Efi is perfect and there is no way I will disturb anything. Can it just be sanded and sprayed with clear? Is high temp paint required there? It’s been in the carport for 2 weeks with rainy weather and happened fast.

 

[Don Frelier]

Clear would work.
No that part wouldn't need to be high temp.

Just get a pint of orange engine paint and brush it on .... it should flow out good and leave no brush strokes. . Both my engines are brushed, valley pan is smooth !

I would just leave it natural finish but wipe it down with clean engine oil or spritz some WD40, wipe it afterwards.

Aren’t the valley plates aluminum?

 

[Dennis H]

Wow. I just ran out with a refrigerator magnet. It sticks. This particular one is not aluminum.

 

[5.7 hemi]

Gee Dennis, just gotta take the wind outta my sail? Lol!!!

 

[GetX'd]

I thought they were aluminum too Zack. Dennis has a “special” one........lol

 

[Dennis H]

Other half says she never saw anyone run that fast with a magnet. And I limp right now.

Don’t know those products.

Don't be tripping on those steps and re-aggravate your sciatica!

Don’t know those products.

RPM is made by someone You don't like & whose name is not to be mentioned by mngm'nt threat of being banned. But the product works. Clear is going to peel & flake in a couple years or less, paint will maybe last a bit longer. Consider a rust converter like
POR-15 or SEM Rust Mort. Not sure about POR, but Rust Mort can be sprayed out of a gravity gun.
If You clear or paint it, I would use something more aggressive than Scotch-Brite to prep. At least 320 grit, but better yet 280 grit, leaving the scratch pattern in long uninterrupted strokes, no circles.

It's called patina, which is all the rage today. In fact, sprinkle some salt on it to accelerate the patina. In fact, take your vacuum cleaner bag and shake it around over the entire car and everyone will go gaga over it.

Naval jelly, clean thoroughly, then wipe with acetone. When dry, spray paint.
