Well so far its holding up quite nicely, I use a high volume flood coolant pump and the enclosure has seen 50+ hours of flood coolant operation with some way oil contamination thrown in with no leaks. You make a good point though, I wiped all joints down with alcohol prior to applying the silicone which is a good idea for any silicone application. It sticks to the fiberlgass like a weld, I don't see it failing.
I use Tri-Cool 1 synthetic water based coolant, maybe some of these other coolants would attack the silicone, I can't speak to that. |
