I'm sure this has been discussed to death, but I am wondering whether I could use aluminium bolts and zinc coated clips for the engine undertray and rear diffuser?

 

Cheers!

I use nylon washers.

Before understanding galvanic corrosion, I used S/S and managed to corrode the tray slightly.

 

I now use BZP washers, spire/c clips and button heads, all with a bit of copper slip.

 

I assume you are considering aluminimum due to corrosion resistance, but they could be a total and utter nightmare if you strip the threads, which is likely over time with alu.

 

I would do as I do but hey, what else am I going to say

Ormes - sounds ideal to me!  What about the bolts themselves - mild steel, BZP, or stainless?

I just use BZP everything, including the bolts

I use the quick release fasterners that A4 bolt man does. Can't remember his website to post a link but they are great IMO. I think these are a plated steel clip with a chrome plated steel pin which also has a nylon washer.

i just used nylon washers with the standard bolts and washers.

I use stainless bolts and washers with a nylon washer between.
This stopped the corrosion of the alloy. Painting the diffuser has also helped.
