Works as expected on a ford differencial

Little tube seals up a ford Differencial, but at $2 plus the price is high for what you get.

RTV ultra black is very good stuff, probably the best you can buy - but considering the pricetag, you may be better off getting the larger size(0.5oz vs 3.35oz). I had a very small repair and it was perfect for the job. If you need two you already paid more than the large size. Problem is the larger size dries out if you don't have another job within a year or so.

              A must have when breaking into your vehicles engine and wanting to ensure there are no gasket issues once the job is complete...leaks. Used this stuff to reinstall the valve cover gaskets on my 2005 honda civeic. While i replaced the gasket during the process, this is the recommended sealant to apply in those pesky corners of the valve cover to ensure there are no sealing "breakdowns" once everything is re-installed. This silicone seemed to apply easily and it just takes a small amount. This product should be in any DIY mechanics tool box as it has multiple useage/applications

                  Comments about Permatex Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker (.5 oz):

                  I bought this product because I thought oil resistant meant it was usable with all petroleum products. However, after using it to install a jet in a carburetor, I found the "fine print" that said it wasn't recommended for contact with gasoline. That's contradictory. The product also has the consistency of light grease which makes it a little difficult to shape. It has a 24-hour cure time, making repairs a lengthy process. I suppose this product would be fine for water or air systems, but why Permatex claims oil resistance and can't be used with gasoline is a mystery to me. I have nothing bad to say about the product itself, though, if you can figure out what it might be used for.

                    Can you just use this only to make a gasket without actually using a gasket plus this product

                      Yes many people have used this product alone as a gasket without issues. Be
                      sure to use enough to form a seal though. I used it in addition to an
                      actual gasket since most gaskets are dirt cheap (On amazon at least).

                      Yes, it is a gasket maker. It helps for surfaces to be flat. Surfaces need to be cleaned with brake parts cleaner so that they are oil free. Works great!

                      No. When using a paper or cork gasket, use the permatex grey sealant. Use the black rtv either by itself or with a rubber gasket for best results.
