Snelle levering
Snelle levering, product doet wat het behoort te doen. Gebruikt voor de dichting van een differentieel huis van een BMW E46 sedan bij het vervangen van de rear diff bushing.

Succeeded where a traditional gasket failed.
I bought an aftermarket differential cover for my Silverado, and after trying two different OEM gaskets, it would still leak. I ended up buying this product to get a good seal, and it worked exactly as it should. No leaks, no slow dripping, just a total seal when the gasket couldn't get the job done. I also didn't need to wait the full 24 hours for the RTV to fully cure. I followed the instructions as listed, but I gave it 5 hours to cure. I think the 95 degree Texas heat probably helped speed up the curing process. Regardless, this is a great product and it does what it's supposed to do.
