Essential for a secure fit without the headache
Used this for a PCV valve installation on my 4runner, and it’s exactly what I needed. Since this stuff is oil-resistant, I don't have to worry about it breaking down in the engine bay. The best part about the Blue 243 is the peace of mind—it’ll keep the valve seated and prevent it from vibrating loose, but I shouldn't have a tough time removing it later when it's time for the next swap. It’s a solid middle ground between "vibration-proof" and "serviceable." If you're doing your own maintenance on a Toyota, this tube is a must-have for the toolbox.

Good stuff, really works better than the 242 on stainless and oily environment
The 243 formula really makes a difference when used on stainless and other corrosion resistant metals, even with oil or grease contamination, like that you often get in tap holes of anything mechanical like engine, bikes, gears and sprockets, motors, etc. Using the 242, I often observed very poor, if not total lack of thread locking, when using stainless fasteners or in a shop environment, anywhere around greasy or oily parts. With the 243, I still yet to have a failure in thread locking and I've been using it for over a year now. 36mL is a lot cheaper than the 6mL tube and no, it won't go to waste because you used it once a year ago and are afraid it's no good anymore. Simply cap it off properly and it's gonna remain usable for a very long time. Don't forget to shake it up before using it that day, just like you would shake and stir your paint before painting.

Bueno
Muy buen producto. Les aconsejo agitarlo y al final sacudirlo hacia la base, con la punta hacia arriba ya que de lo contrario la diferencia de presión de la burbuja de aire dentro del resilience puede hacer que brote el contenido. En mi caso el producto fue algo espeso y tardó en asentarse. Cumple su función a la perfección. NOTA Cuenta con una indicación de ser posible generador de cancer .
