Gasket genius: We need you now!

DOT5 doesnt absorb moisture so this will cause rusting as the moisture isnt absorbed (kinda doesnt make sense but its still in there) DOT5 used to not play well with OEM rubber. That was the myth when it came out, but others have made the switch and not had issues. DOT5 is also (reportedly) more spongy when it comes to brake pedal firmness (cant be used in anti-lock brakes with fast modulation) . 5.1 is still glycol based, just the best temperature rating. I dont know, never used it but going to a remote reservoir Neon type MC is a plus as they dont leak (why not?) and they dont seem to corrode as they are plastic where they may vent (at the caps). Magnums went to a machined gasket rail and rubber gaskets on the valve covers, this was an expensive operation when trying to save a buck but they did it anyway....wonder why. Cast gasket surfaces suck!

Right, but you still don't mix DOT5 with any of the rest. That's not a myth. So if you're gonna use it the system either needs to be new and dry or flushed to the nth degree....how you would do that, and get all the DOT3 out, I don't know.

DOT5 is good stuff. "They say" it gives better pedal feel and all.....I've never noticed it....maybe my foot ain't sensitive enough. Matter of fact, Matt just called me recently askin about it, thinkin about changing to DOT5 on his builds for the paint reasons. All of his builds have seriously nice paint work so he has an interest there.
