No, you're right, I dont clay it every month. In fact, i clayed it and used the cleaner (mothers step 1) only the first time. The other times, I just used steps 2 and 3 after a proper wash. It's smooth as glass without swirls, except where the bird crapped.
So is mothers step 2 (sealant/glaze) not the same sealer as what you're talking about?
