EFI Intake coating?
1990 5.0L from an F150.
What is the (shiny grey) coating made of that is on the EFI intake manifold?
I just pulled said motor to rebuild and detail it (for my 54 F100) and some of the finish is cracked and a little corroded underneath.
My intent is to paint the intake (and motor) but what do I do about this cracked and flaking finish on the intake?
Do I try to peel it all off and get down to the aluminium or try to patch the damaged areas?
If the answer is patching - then with what?
Thanks,

I believe it is just a clear coat finish to keep the aluminum from oxidizing. You can use aluminum acid cleaner to remove it and then respray it with high temp clear paint if you want the shiney finish, or leave it natural.

Thanks for the response, been real busy offline lately.
This coating that is cracking/flaking in a few spots seems pretty thick - like 1/32" or so.....
Where would one find "aluminum acid cleaner" ?

Any parts store. Eagle One Mag cleaner works pretty good. Get the one for Mags( it has green wording on the lable ) it is the strongest, they also have an aluminum wash for anodized and coated wheels. This is too waek to do what you want to do. The Eagle One is the only one that I use. I had a set of CenterLine satin finish Auto/Drags on the 69 440 6bbl Road Runner that I used to own. Sprayed that stuff on there and in 2 minutes after hosing them off, they looked brand new, every time!!.
Just read the instructions well and don't get it on anything painted and you'll be fine. You may have to use a scrub brush or something to get all of the coating off.
Good luck, let me know how it goes,
Jimmy
