One of my vehicles threw a P0420 code today, and started overheating about two hours later (coming home from a trip). Is this indicative of a clogged cat? I'm wondering if this procedure would also work on a clogged cat after all of the pieces have been removed.

Another related question that may have been answered: are there proper methods for disposing of the leftover mixture after the cat is cleaned?
