I just kinda wipe Rain-X paste on my front windshield every 6 months....works well enough for me. During most rain storms, I don't even need to turn my wipers on.
I know the question was about "not Rain-X", but why the aversion to the product? It works well enough for the price point it's offered at. Sorry if my question is pushing some sort of button, for once I don't mean to be a troll.
