Best RTV Ever made
This is the best gasket sealant money can buy. It's not goopy, it doesn't seep, it doesn't take up so much room that it deforms the gasket when tightened, it isn't impossible to clean up, IT JUST SEALS! It seals everything, head gaskets, valve cover gaskets, oil pan gaskets, nothing is better. Silicon RTV is junk, if it's not applied perfectly, IE not too much, not too little, in all the right spots it will seal, for a while. Since a master semi-truck mechanic I drag race bikes with told me about it and I tried it, I'll never use RTV again, only anaerobic, it's what all OEMs use now anyway.
Most Liked Negative Review
No I would use different product for reason above
Be careful if you are marching up with aluminum you will need per manufacture to spry on a activator

Staff Reviewer -
this is stupid to ask. I just told you easy to use, like the product because it works well.
Bottom Line Yes, I would recommend to a friend
Worked as advertised
Staff Reviewer -
Used it to seal a gasket on a carburetor rebuilt worked great.
Bottom Line Yes, I would recommend to a friend
Worked perfect
Verified Buyer -
sealed up the oil pan on my 05 Volvo with this, no leaks. I used a foam roller to evenly spread it around
Great for dressing gaskets!
I used a very thin film of this sealant on the water pump and water outlet gaskets on my 1991 300D. Worked great to hold the gaskets in place during assembly and is peace of mind for a perfect seal.
Bottom Line Yes, I would recommend to a friend
Same as Loctite 518
Verified Buyer -
Red so adds HP. Smells like cherries. If you have good surfaces use this for your crankcase instead of yamabond or other rtv goop.
