fittings in aluminum WP housing

I know it's a good idea to use never-seize on bolts, so i assume i need to use some on the heater hose fittings and temp sending unit? well...that's brass so maybe not.....

Never seize is a good lube, but a poor sealer..Liquid teflon sealer is what you want..Probably on the same rack as the never seize. With that, it seals, and will still come out in 10 years...You know, when the hemi goes in...
