A few very basic questions regarding seat removal for AP2. I want to remove the seats mainly to clean everything underneath and around them and maybe grease the rails somewhat. Questions are,

1. The bolts locking down the seat are somewhat rusty looking... the car has endured some Michigan winters after all. Are they a standard size/type such that I could get some shiny, affordable replacement ones?

2. I understand that I should use some liquid thread locking material when bolting the seats back in. True/false and if so, any suggestions?

3. What's a good grease to use to grease the rails? My seats don't move forward or backward all that well nowadays due to dirt/grime; this was one of my main goals in doing this exercise...
