I just cleaned mine with strong soap and water and scrubbed it off. Then I used a green 'scotch-brite' pad and sprayed it with gray primer. Don't know if it the right way to go about it, but looks a lot cleaner.

you need a primer that will work with galvanized metal, it used to be a special paint but maybe it is mixed in with regular primers by now? My trucks paint flaked off the galvanized cowl because it was not prepped right.

I am not promoting any particular product. I visited one particular manufacturer and this is what it said;

The cowl is GALVANEALED which is a different process (hot and baked) than galvanized (which is just dipped hot or cold).
It's still usually called galvanized to help with those of the general public that don't know any better.
Irregardless (I love that non-word) it (galvanealed) doesn't take any special procedures to prep and paint unlike a normal galvanized panel.

I personally never did anything special besides normal Etching Primer and Primer Sealer.
No special washes or anything.
My first paint job was shot in 1993 and was perfectly fine in 2003 when I re-shot the truck a darker red. Then I did a total repaint to all black in 2008.
I've never heard of the factory paint having problems, just re-paints by DIY's or places like Maaco.
Now the late 80s to early 90s Ford and Chevy paint jobs... yikes!

Mine is a 1978 and it has 3 layers of paint (from previous owners) and all the layers peeled off the metal around the vents below the windshield exposing the GALVANEALED metal(I learn something new everyday). It's at the bodyman's since July, I'll get it back before October (I hope!). I'll ask him how he prepped it next time I talk to him.

If it is real galvanized metal you can use white vinegar or if you really want to prep it meratic acid, use gloves dont breath it in. it has quite the reaction. I use meratic acid in my sheet metal shop to get it off for paint. what i do is pore some in a cut off 20 ounce bottle then take a few small peices of metal put it in the bottle and stand back and let the reaction happen, it cuts it down so it isnt so potent. then I just wash it off with soup and water let it dry and if it has lost its shine its ready for paint.

When I painted mine 20 some years ago I sanded with 220 and them used a product called Metal prep. I believe House of Kolor sold it at the time. I have had NO issues with peeling, flaking or otherwise. John
