Two things.  GO with Ate Superblue or the BMW OE stuff from the dealer 
(Same stuff different color... I use both and alternate which color I'm 
using so I know when the system is flushed out) It's Boiling point is 
significantly higher than the LMA.

THe other reason that the pagids boiled is that the Cool Carbons have a 
Ceramic heat barrier in them and the pagids do not.


Later!
