pre note; i might not have googled for very long before coming here.

I'm looking for new fastners for the undertray. a few have disappeared over the years (think i'm down 3 or so). is there a quick and cheap alternative rather than paying a shop in europe and waiting a month for them to arrive? I'll need both the screws, washers and something to secure them into (nut or something). is this a terrible idea?

additionally, i might be missing one or two clips from the front nose grill / radiator grill intake.

thanks in advance.

Ace Hardware. Love that place.
It's where I go. Surprisingly large selection of stainless steel stuff too.

Just picked it all up from Ace replaced with all stainless steel. Had to go to a couple different ones as they didn’t carry enough in one store.

The one gotcha I've seen with the undertray and diffuser hardware is that you can indeed get dissimilar metal corrosion between the steel or stainless washer and aluminum panel.

The problem is that aluminum is much more electronegative than ferrous (including stainless - nickel is about as electropositive as iron) metals. These metals in contact in the presence of moisture will quickly corrode the aluminum. So while stainless washers and bolts are a great idea under there, you do need to do something about the contact between the dissimilar metals.

A quick fix that works well for cars that seldom get wet underneath is just to smear a little 'silver' anti-seize compound on the coin-sized patch where the aluminum panel is touched by the washer. This should take care of most of the issue. A more elaborate solution would be a plastic washer between the metal washer and the panel - I may well do this, as it would be a minimal weight addition.

You should be using a little anti seize compound on the stainless bolts anyway because, while they're stainless, the clip nuts and threaded holes on the car are ferrous and will corrode if given the opportunity. Some anti-seize there does make the next removal easier.
