I had these guys do their "rustoration" on my Tacoma and LC. Seems like they did a good job and I haven't had any rust progress since. Plus, lifetime warranty.

Can you post pics of the underside of your LC after the "rustoration"? I've been using Krown for the last few years, but there's still more surface rust under my rig than I like.
