2002 WS6 Rebuild
First time post and hoping to get some direction. I bought a 2002 WS6 off of Copart and currently working on it to get it back on the road. Currently it's in the shop for rust repair as I stripped the interior to the sheet metal. Currently they've take a foot out of the passenger side floor (photo below is the initial they've cut more since then), half a foot out of the driver side, fabricating new wheel wells, wire wheeling interior/exterior, killing the rust and then coating. When it gets back I'm installing OC Carpet replacement kit, new factory style audio and reupholstered seats.
My question is with the bolts that hold the seat belts in place that bolt to the floor. As I understand the thick rubberized coating bound up on each bolt is OEM intended to both keep the bolt from rusting and to keep the elements from the outside from getting inside. Can anyone advise what that coating is and what is the modern equivalent i should be using when I put everything back in? I posted some of the rust spots.
