Did the job.
Follow the instructions and you should be good. I let it pre dry as suggested at low torque. Then torqued to spec. Let for 24 hours and the sump on my motorcycle no longer leaks. Obviously you need to do a good cleanup first and degrease. Then apply a think bead all the way round and surrounding any screw holes.

Good, but too slow to cure.
Affordable, easy application, squeezable tube, but extremely slow to cure that it definitely needs more than the 24hr claim. I'll no longer use it for a quick gig.
