Permatex Ultra-Grey at car places

Yama-Bond at Yamaha places..

Best stuff when you want it NOT to leak..
Use sparingly
Read instructions

Wipe off excess--should there be any...but shouldn't be..

Yes...It is the same thing as the Ultra-Grey made under licence from Drei-Bond GhmB...
(If it's what I think you're referring to) It just costs 5-7 times as much..

Interesting. Isn't Ultra-Grey actually gray, though (FIPG is black)? I mean, I guess coloring isn't hard to add. FIPG is definitely expensive, but it's amazing. I have used it for water pump gaskets, oil seals/gaskets, and even patching a hole in a CV axle boot once (lasted for 20,000 miles, until I got rid of the car - probably still fine...). Turns into a pretty tough rubber-like substance - also sets really quick, which I like.

Yeah yeah, done a side by side comparison? There's some lunatic here that constantly screams about it and if I recall correctly I flipped over the tube of the stuff and saw "Made Under licence from Drei-Bond GhmB" ...

Have you used Ultra-Grey or Yama-bond?
 
Ultra-Grey, 3-Bond, and Toyota FIPG are all a little different. They might all be made by the same company, but they definitely have differences in viscosity and tack. So choose what you want for the application. I have 3-bond, Permatex Moto-Seal, Ultra-Grey, and Permatex FIPG. They get used in different applications.
FIPG (even the generic permatex) is the shiznit for sealing flat machined surfaces, removal might require a hammer or pry tool. Ultra-Grey and 3-bond/Drie Bond are good for that as well, with the added benefit that they work on the OD of seals.

Perma-tex Black/Blue/Red is just RTV silicon rubber... I like the blue cause i paint lots of blocks blue.. I do not like how RTV silicone rubber doesn't stick so well to things..
it is good for caulking around the sink or the bath-tub..

Ultr-grey for things I want permanent-ish
Hylomar or Loctite 510 for things I think may come apart in the field some day.

I usually use RTV is when a HIGH temp seal is needed, I then grab the tube of Permatex Ultra-Copper. You can make header gaskets with that stuff! Good to 700F! I've also used it on both sides of valve cover gaskets for b230s with great results.

Black works surprisingly well on diff covers. It seems to be a bit better when there's a little oil residue left over.
 
No sealant needed for the front engine seals. The water pump uses a gasket against the block. Again, no sealant.
Get the crank, cam, and intermediate shaft seals from Volvo.
 
^^^^ Correct. Don't glue your seals in place. The next guy, likely YOU will have trouble pulling it and may damage something. I have had to fix two damages engines recently that wouldn't seal because somebody scratched a sealing surface with a tool. Its not fun ripping apart FWD V6 engines two or three times to chase the same oil leak.

Do you use these sealants with gaskets, John?

I've been trying to figure out what's best to use on things like valve covers and dirt bike clutch covers, i.e., stuff that I want to be able to take apart and put back together without replacing the gasket. I've used wheel bearing grease on some, and some with Ultra Gray on one side and grease on the other.
