Very good stuff, must have for any mechanic.
If you’re not familiar with this sealant it only hardens once everything is tightened up, it’s like a heavy grease when you apply it. I’ve had excellent results using it on split engine cases and as a replacement for a base gasket when you are trying to bump up the compression on something like a chainsaw or other small engine. What i use it for most is on paper type gaskets. A light coat on both sides of a new gasket and it’ll never leak. In a pinch if you pull something with a paper gasket and it don’t tear you can apply this to the exposed side of the gasket and re use it. I’ve done this quite a few times and never had a leak. It is better than using Silicone/RTV in a lot of applications. However I would not recommend it for any application that has a rubber or steel gasket.

This permatex anaerobic gasket maker worked wonders. It's been 6 months since I use this and the seal is still perfect.

Dependable, easy to find and works great!
Seams to be working great, no sign of any leaks so far. Because it's a Permatex product you can find it just about any where, unlike some other products like Honda Seal or Kubota's proprietary goop. Plus it's Cherry Red and delicious !

An honest review....decent product for aluminum
Ease of use, sealed things up....ran just a bit short. So could be just a smidge more in it for the price. Looks like more than there really is...so yas all know.

Works well
Works well. Please note, if you have never used this anaerobic gasket maker before, you will also need to buy the activator spray. This is noted in the assembly instructions.

Funciona bastante bien
Excelente sellador, funciona bastante bien, Yo lo ocupo para sellado de monoblocks de autos donde la tolerancia es mínima, y no me permite otro tipo de sellador.
