hood pin corrosion/bubbling


Recommended Posts

I installed the Shelby billet hood pins yesterday. When I pulled the stock pins I found some of the paint corrosion or bubbling described in other posts. The pics below are the best i could get, but it kind of shows the bubbling around the screw holes. Is there something I should do to correct this or to prevent it from spreading? Any advice is appreciated.

Aluminum oxidizes; when they drilled the holes in the hood they left the exposed aluminum untreated and this gives a point for the oxidation to start. It will lift the paint and expose another area to oxidize and so it goes.

I think it is galvanic corrosion between the steel screws and the aluminum hood. Aluminum by itself should get a skin coat of corrosion and stop corroding, at least the alloys on big aluminum fishing boats do...

Makes me want to pull my pins and check though.

So, are there any thoughts on what to do about this? I guess my biggest concern is that it will continue to spread out beyond the hood pin plates. I guess if it does this within the next 2 1/2 years it will be a warranty issue. Should I just keep an eye on it, or is there something more proactive I could do?

mine goes in next week for its 3rd replacement scoop and 3rd full stripe set they will also be taking care of this issue under warranty also at the body shop, i assume they will need to remove and repaint that area. i feel every issue mentioned by owners no mater how smaLL should be checked and treated accordingly by all owners as our warranty just keeps ticking away. how do we go about getting sai to extend its warranty due to so many issues only now showing and other taking so long for fixes.

Yes, if they used steel/galvanized screws they will have a reaction between the two metals. I had a box van that had a steel frame and aluminum box and anywhere the two metals were attached there was a reaction and the aluminum ended up with a big hole in it where a screw was. Since this is an aluminum hood they just could use aluminum screws with aluminum hood pins and plates that would help.

yes that's them, look awesome compared to the stock plates, until they faded :(

VEGASTY,

 

Canceled my order for the Shelby black hood pin kit after receiving an e-mail from SPP:

 

Hello Mike,

 

We are currently sold out of the black hood pins that you ordered. We are in the process of finding a new coating for them, as the anodized pieces were known to be faulty. You are looking at probably 3+ months before they are available again. We can swap them for the regular billet pieces if you’d like, or take them off the order completely. Let me know what you would like to do as we have them set to ship as soon as available. Thanks and sorry for the inconvenience!

I replaced my hood pins a few weeks after I bought my car and I used aluminum rivets to secure them. I haven't had any problems with mine. I don't think that screws are the best thing to use for hood pins. My stock hood pins had rivets also.

 

Shelbybro, how about posting a pic. Just curious as I've never seen a SGT with riveted hood pin plates. Thanks

 

Jim
