I've been told to look for vacuum leaks in the s-boot and fill any cracks with silicone. There are also several hoses that are simply NLA for which there are some crazy fixes.

My question here is:

Has anyone used that flexseal stuff I see on TV to repair any vacuum issues on their s-boots or hoses?

I'm curious to see how that stuff works and I'm wondering if anyone's done any damage with the product yet...

Thanks.

do not use flex seal for anything except floating a boat with a screen door bottom. there are plenty of other very good fixes for all hoses, just may not be Original looking . but may also be a better fix the factory. :D did i just say that. :shock:

Not sure what the flexseal is you see on TV, but I have been using a caulking compound called Flexseal for many years with great results. It comes in a standard 10.1 ounce tube that you use with a caulking gun. It bonds tenaciously and stays flexible for at least a decade in the sun.

Don't know that I have ever used it on the mechanicals of a car, though it is possible I have. It is nasty stuff to work with as it readily bonds to your skin and will ruin any clothing it touches. It takes quite a while to dry as well and does shrink so a second coat is often needed to fill a gap.
