Aluminum hood....
I'm looking to get an aluminum hood for my na gxl, I did some searching and saw that you have to use the aluminum hinges and aluminum latch. Is that it or is there something else you need to do?

I just did an aluminum swap too. A few posts suggest using dielectric grease and grounding it to the chasis. You should get the latch for aluminum hoods as the steel latches have harder springs, it is very hard to close without one.

I was in a fender bender, my car had an aluminum hood. I found a replacement in a junk yard. The paint on it was bad, so they guy charged me $80. I traded it for a different aluminum hood that matched my color from a different FC owner.
Maybe I should go back and get the hinges and latches for someone else to buy.

So if you need to use aluminum hinges and latch so that the aluminum hood does not rot, what about the hinges? They are connected to the steel frame, so wouldn't they start to rot?

Intresting the S5 models only list one hinge (the same P/N as for the S4 steel hood hinge) for all hoods, so I don't know if the hinge is that important or if Mazda just was cutting further corners on the S5.

How does the aluminum hood rot? Just rusts quickly?
And is it confirmed positive about using dielectric grease on the hinges to keep the hood in good condition? My hood was recently switched and I hadn't heard about this yet.

A lot of people talk about aluminum hinges to prevent galvanic corrosion but the bolts and pivots are still steel.
There may have been some reason for the factory to do such a thing but I didn't bother and I haven't seen any indication of a problem. The paint seems to be enough protection.
I didn't notice a big difference on the latch either.
If you have access to all the right parts, go for it. But has anybody ever seen an actual problem with the steel parts?

On second thought, I could imagine a different hinge that will prevent the hood from going through the windshield in a front end collision.
Aluminum and steel will fold up differently...

Right, I meant that I didn't notice a problem with latching or unlatching an aluminum hood in a latch meant for a steel hood. It probably doesn't work as well as it could but it's not that bad.

only really works if the anode is the same size or smaller than the cathode.
