I'm putting my truck back together (lights, mirrors, grill and drip-rails) and am trying to get the right fasteners.
Looking at the fasteners I removed, some like the DR ones look to be the black kind and a bit rusty, some like the roof light are shiny an non-magnetic (I assume SS). The wheel-well trim screws that are always a bear to remove are magnetic and shiny and look OEM (nickle-plated?).
So I ask: What's the ideal fastener material, and more importantly what reaction will it have to metal it is being screwed into? (Ex: on body sheet metal, I'd much rather the fastener rust than the body)
Secondly: What could/should I dip the fasteners in when re-screwing to help seal out moisture (this is especially important on the DRs), a silicone or Right Stuff?
Thank you!
