I have the same problem with my Integra here in IL. I have a bunch of old slider pins and boots as one of them always seizes - somehow the water leaks in. The Helms manual actually says to check and relube the slider pins every 6 months. I would say to replace the bolt, use the permatex anti-seize like you did and check the boots to make sure they're sealing the water out. I actually used gasket maker to coat the outside where the rubber boot meets the metal.
