Ok, let's begin.
While it did sit on my shelf a while, it was UNOPENED.
With that being said...I come to realize that the BASE GASKET WAS NOT CORRECT! it's for a Yamaha 1200 waverunner PWC...not a snowmobile.
2nd the O-rings for the coolant cover are SMALLER diameter than OEM which allowed coolant to leak. Had to reuse the old O-rings.
All in all, if you had to use this brand...it'll do in a pinch...but I would recommend AVOIDING COMETIC all together
