Great product, works well

I used this on this for a valve cover gasket and it worked alright. The tube basically blew out the back end when squeezing so be careful. But other than that it was fast easy and dried quick, which is what I needed. It’s as easy to remove as most siliocine caulkin. And it stuck pretty good. You get a decent amount per tube. More than you could ever need for 1-3 jobs. And the color was what I needed, but if you’re using this like you should, the color should matter as it’ll be hidden for the most part. Over all, it’s good but I which the actual tube it’s held in was More durable, no reason it should bust open just from squeezing it. But the size is good, you get a lot of it.

Works well, it's good quality silicone so should last not a gigantic container so keep it in mind if you have a large area to apply. Also if you try to squeeze the tube to strongly you'll pop the tube seams. Super water resistant and good consistency.

The ULTIMATE black is the best working and curing product I have ever used from any RTV manufacturer. It smooths on like soft butter with no clumping, excess cleans off easily, and it cures into a true rubber-like material. It makes great gaskets and sealer. The only other RTV product I buy now is the extreme high-temperature red or copper. J-B Weld Ultimate Black is not formulated for high-temperature use on vehicle exhaust headers and connections.

Love this stuff, it is so useful in many applications

Works like it's supposed to I use it all the time on certain projects

Es el mejor producto

It's nice no smell too much and bonds very fast

Cumple las expectativas

Me sirvió para pegar en mi BMW y lo soporto ya que se maneja temperaturas altas, 100% recomendable

Only the casing is a bit abused
