    Have been using this for years at previous shop. Works very well and seals engines , transmissions, and differntials. All we ever used was high temperature Red. I decided to get the black and one can of blue. Black works as good as the red on sealing

    I would like to see some high temperature grey as I service a lot of diesel engines

    Works like it says.

    This product is as good as I figured it would be. I use the tube RTV on a daily basis and I have been trying to get my employers to buy these cans to help stop waisting the ends of the tubes. The description should be a little more clear however. It says “6 to a case” so when I ordered I thought I ordered a “case”. In fact if you have a quantity of “2” then you get 2 cans. Just an FYI. Wish it would have been a little more clearer. All in all, performs it’s job like it says.
