The uppers are made to last as long as the boot doesn't get ripped. Once it's ripped, contamination gets in and that's the end of that haha
For the lowers, either soak in PB Blaster or use Kroil (all of my friends swear by this stuff, can only get it from Kano Labs). Give each bolt a spray, maybe a light tap with a hammer, and it should be easy as cake to get em out.
I need to order some. If you don't have any, douse in penetrating lube, tap with a hammer, lube again and an impact gun if you have it. Impacts are nice
