they don't make my mower blade brakes anymore but I'll keep just applying this to the old pads every few years and I'll never have to replace the brakes:)

Works great

I used it to seal the strut and tracking fin to my ski boat. I haven't taken the boat into the water yet but as far as I can tell the sealant cured great and is gonna work fine. The thing that worried me, is that the package states it must be used within 24 hrs of breaking the metal seal. I haven't tried to use any of it beyond 24 hrs so even though I capped the tube and put it in a ziplock bag I don't know if the resf if the tube cured and is no longer usable.

This stuff is amazing but thick so it takes a while to apply but we'll worth it. It might be worth it to get an electric caulk gun if you have a lot to do.
