Hood Pin Corossion - Repair or Replace Hood?

[rmarks]

I have the dissimilar metal corrosion on my hood from the hood pins (both).  One Ford body shop says they can fix it and another says I need to replace the hood.  What have you guys done?  Can the aluminum hood be properly repaired?  Recommendation?

If you do a search for corrosion you will find lots of posts, options and solutions.  I’d find a salvage or take-off and replace it. Likely cheaper than all the work needed.

And you'll also find lots of info on changing out/placing/attaching the scoop during your search.

I have the same problem. I'm planning on replacing the hood with an oem style carbon fiber hood from anderson composites, painting it, and putting the hood scoop on that hood.

Great point and note which version of the scoop you have by looking under the hood blanket.

I thought the 2008 with the updated pins didn’t have the issue?  I’ll have to keep my eye on mine, I switched my stock ones to the upgraded like the 08 and thought I would be OK.

The 2008 model used steel screws on the aluminum hood causing the corrosion. It is also caused by ferrous material contamination prior to Ford painting the hood. These hoods were not properly prepped prior to paint. The aluminum reacts with the ferrous material under the paint causing it to bubble. Ford has a technical service bulletin for the issue but will not fix it. There was a class action lawsuit that was thrown by the judge. All of the forums I read said the corrosion will come back. Carbon fiber won't corrode and it is cheaper than a stock hood replacement, so that's why I am going that route.

I switched to aluminum screws when this was first reported. No issues but once it starts, and it can be triggered by contamination at the factory, the hood needs to be replaced.

I too , experienced the corrosion and bubbling of the paint on my wife's 06 Mustang on the left front edge of the hood.  Took it to the selling dealer's bodyshop, and the car was already out of warranty, so they really didn't want to do anything about, but the manager was trying to be nice, and we did buy a fair amount of cars from that dealer.   So after a little more convincing by my wife and I, the manager said they would meet us half-way on the cost of a repaint on the hood, so we decided to go that route.    Then about 2 years later we decided to sell the Stang and you could just start to see the bubbling paint starting to come back again in the same area as before!  This hood had no hood pins in it, and I think it was just poor preparations by the factory of the paint process, also the manager some-what admitted that the bodyshop really hadn't had proper training in handling the aluminum painted hoods bubbling and corrosion.    I told the manager that I kind of find that kind of funny because Ford had recently announced their new F-Series were going to be made out of Aluminum, so I looked at the manager and wished them good luck with that!!        P.S.   If you are the type of collector that wants to keep your "Prized Car" Pristine and Flawless" for a long time , I think you might want to use some other material for your hood than aluminum, unless they can get better with their paint fix in the near future!!!!!   LOL.     J.M.O. 

Later!               "MONGOOSE"

I was told the 2008's had updated hood pin units. The white hood in the photo is a 2007 SGT that had the old style hood pins and screws.

My 2008 SGT came with the Shelby brand hood pins.

The billet hood pin sets from Shelby (Drake) cam with stainless steel screws, I believe the 2008 SGT's  would have been the same other than the "Shelby" script that was included on the 2008's. Shortly after installing my billet hood pins I switched the stainless screws out for a set of aluminum screws to hopefully fend off the corrosion.

I don't know of any difference, screw material wise, between the 07 and 08.  I'd have to look back and search the threads but if there is any concern I would order a set of AI screws. Years ago we all went in and bought a few hundred and passed them out....cheap insurance.

I believe I still have 40-50 of the aluminum screws from when I bought a box, I can send some out to you if you like.
