Actually I've used the Permatex/Locktite tape a lot, but like the factory rep said, you have to start it a thread or two back tapering the windings, and most importantly, wind it on in the proper direction so it stays put. Been a life-saver winding it on thick on certain worn out sloppy hydraulic fittings.
I have used it extensively as well. I have also seen cast, and especially aluminum housings split wide open because someone overtightened a fitting with tape on it. Having been in the oil and gas industry, I have gone through more teflon tape than I care to think about. I simply tried to keep the OP from ruining his filter housing.
