Red RTV
Great product. Needed a sealant in place of rubber or cork seals that are known to leak on an old Land Rover engine rebuild. Cleaned the surface and applied. Very good seal that was tested with a pressurized smoke machine to confirm the seal. Great for areas exposed to heat and oil or petroleum chemicals. This is now a standard in my garage.

Pretty good RTV
Makes for an easy application of RTV in a shop or garage environment. The easy applicator nozzle did not work at all on the can I got. I ended up taking off the black trigger thing and just using the nozzle like cheese in a can. Made for a quick and easy application on heavy duty vehicle hubs.
