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!
