VEGASTY Posted March 17, 2008 Report Share Posted March 17, 2008 today i noticed a kinda bubble about 1/4" peaking out from under the hood pin plates, i unscrewed it and low and behold each of the 4 screw holes now had bubbling spidering out from each hole, i'm guessing rust growing under the paint from water reaching the un-protected metal where drilled. sorry my camera is busted can someone check theres and see if same issue as me. thanks Link to comment Share on other sites More sharing options...

I removed my original plates at about 4 months (actually 9 months after production) to replace with the billet plates and no problem at all. Actually it can't be rust as the hood is aluminum. Sounds like a warranty problem to me. Let us know what you find out. Jim Link to comment Share on other sites More sharing options...

Jim Same there...I replaced both of mine around 3 months and didn't see anything like that and has been pointed out the hood is aluminum but I could see stress doing something like this over time if the aluminum was flexing. You do remove the pins before you open the hood right? Link to comment Share on other sites More sharing options...
shelbytexan Posted March 17, 2008 Report Share Posted March 17, 2008 problems-problems-problems,isn't it about time shelby replace the whole hood.about the time we think shelby might have the scoop problem corrected here comes the hood pins. i changed my hood pins also and saw no problem but as jeff said with all the flexing you could have problem. i don't recommend putting your hood pins in tight simply because upward pressure on the hood pins could put pressure on the hood.these aluminum hoods are pretty fragile. the original pins were installed loose and that may be why.

VEGASTY Posted March 21, 2008 Author Report Share Posted March 21, 2008 I'll call them "character lines" i had pics taken at dealer for warranty, mechanic said its oxidation from moisture getting under paint from where holes were drilled thru hood, i suggest everone pop their plates to check because i cannot see how this would be isolated to me only, i feel all cars will get this. main issue is it grows that's how i noticed as one grew past the plate, bubbling of the paint. get it fixed before your 3 year warranty is up even if you show tiny bit. IT WILL GROW. JMHO Link to comment Share on other sites More sharing options...
wnenn Posted March 21, 2008 Report Share Posted March 21, 2008 The night I picked up mine from the dealer I swbbed touch up paint on the "raw" edges from underneath. They didn't do it at the factory after drilling the holes through the hood for the hood pins. it is sure to rust if you don't put paint on the edges. Duplicolor comes to the rescue.

sdear Posted March 22, 2008 Report Share Posted March 22, 2008 The hood is aluminum...no rust. But painting them for a cleaner look is a good idea! ok...here's another one. You know how the new billet lanyards have the little swivel piece encased in the plastic?? Nice concept...except....the swivels in both of mine are rusting. Water stays inside those plastic covers...and walahhh ...rust ! You would think those would be stainless steel. I have left several messages with Keith at SPP but no response. Definately going to have my hubby pop off the plates and make sure the paint is ok underneath. Putting some paint around there sounds like a good idea. We did put some primer paint around the holes where the "bolts" use to be under the scoop. Can you imagine what might happen to all those rivets holes ??????????? Ok..i will stop Link to comment Share on other sites More sharing options...

Yeah, I haven't seen this and swapped out my pins and plates myself about 3 months ago. I was taken back by the fact they are just screwed in and there is no finish etc., but I didn't have any paint issues. Of course my car is white and I wonder if I would see the spider effect people have talked about. Link to comment Share on other sites More sharing options...
rnoggle Posted April 14, 2008 Report Share Posted April 14, 2008 Guys, just because the hood is aluminum and therefore won't "rust". It will still corrode. Especially if you have steel screws screwed into an aluminum panel. This is known as disimilar metal corrosion (2 different metals in direct contact with each other) and will normally appear as bubbling under the paint. And it will continue to expand if left untreated. Link to comment Share on other sites More sharing options...

LAter, Clink I use WD40 the same way , learned that in general aviation we used it to fog the wings of Cessnas ..........prevents rust and corrosion, WD = Water Displacement...............just changed my pins to the billit ones , and found no corrosion , and I have put 12,000 miles on my 07 SGT0652 ..................Hope to put a Watts Link on it soon......................ZDS Link to comment Share on other sites More sharing options...

rnoggle Posted April 14, 2008 Report Share Posted April 14, 2008 I believe the stainless screws will still cause a problem with the aluminun. Must likely, for those seeing rust colorong around the screw plate, they have regular steel screws. The best prevention is to put some primer in the screw hole and a little on the screw threads. Then insert the screws while the primer is still wet. This will at least put a small barrier between the screws and the the aluminum. Link to comment Share on other sites More sharing options...
SGT2666 Posted April 14, 2008 Report Share Posted April 14, 2008 I believe disimilar metal corrosion needs 3 things two different metals and an electrolyte, salt is a good electrolyte so any of you in areas that salt the roads or near the ocean will want to keep those areas as clean as possible and or seal it up with something. Galvanic corrosion is a serious issue for Navy aircraft because of the salt. Link to comment Share on other sites More sharing options...
