Best gasket maker in my opinion. Left if for a week because of logistical issues. Did not cure and was able to slap the part on a week later with no issues. Rtv would have dried and had to be re applied

I couldn't get the transmission pan to seal up on my Boxster. It uses a factory paper gasket but whatever I did for cleaning or torque sequence it had an annoying drip. On the third go I used a thin application on both sides of the paper gasket and voila!

Used on a 9.9 yamaha outboard. Crankcase cover and coated the base gasket. Sub 60 degrees F above freezing, no primer/activator. I didn't start the engine for 3 days after installing the powerhead. Used a sheet of plastic to lay the base gasket out and glived hands to coat with sealant. Plastic stayed on my table for 2 days and never set up. I smeared this leftover sealant on 2 washers and clamped then together. It set up fine overnight without being open to air at about 40F.
