hose fittings for aluminum manifolds?

I use liquid teflon on the threads and yes, you want something (not RTV) on them to stop and corrosion or seaping leaks. teflon lets the parts come apart easy - I haven't used antiseize for that before but it would probably work fine too. It just gets everywhere...lol
I use a drop of 30wt oil on AN fittings (aluminum on aluminum) to stop thread galling too.
