This is a useless product, came without a sealed package and completely dried out. I ordered this after reading some reviews that said it was the best thing on the market and these people must work for the company. Don't waste your time, you will be very disappointed with this product, it will not work nor can it when the item is hard as a rock.

Giving this 4 stars for now because it seems to be holding the leak better than other things I have tried.

I applied the product to a cast iron gearbox that had a leak between 2 mating surfaces. To fix it right it needs to be taken apart and resealed but its a big job and needs to wait for winter. I put a slab of this Oyltite stuff along the seam where the leak was and so far so good. I haven't ran the gear box long enough to really warm it up yet so we will see if Oyltite holds through some hard use. If so, I'll give it 5 stars.

I would give 5 stars now but the packaging was crap. The Oyltite paste was not covered in anytype of foil or wrapper, just had the yellow cardboard sleeve around it. This made most of the stick hard, dry and useless. I cut a bunch of the material off with a knife until I could get to the soft part and applied the soft stuff to my leaking area. Probably wasted half the stick. I would also bet that if my leak returns it's because there is a hard chunk or two in the mix that I didn't get worked out during application.

50 years ago I used Oyltite stik to seal a fuel leak that developed in my 1966 BSA Shooting Star fiberglass gas tank that had developed in the seam of the tank near the fuel filler racing style flip fuel cap. I even painted the repair using lime green metallic flake spray paint and never had a problem with it leaking again.

Now I have an oil leak in my 3.2L Mercedes E320 in-line 6, and hope to fill in the area of the head that is leaking. Wish me luck!

Great product, it is even approved for use on our fighter jets to 15 PSI that is!

The transaxle in my car was leaking from the end cover. I applied this to the joint and while I don't think it stopped the leak entirely, it surely did slow it down. It seems like it's a great temporary fix for leaks - especially from a metal to metal joint rather than from a joint with a gasket.

This made the leak in my oil tank WORSE. I had a very slow drip in my 275 gal tank (FULL). As soon as I used this (as directed) the drip got much faster and quickly went from a wet spot to an emergency. Luckily I found a strong magnet and a thin rubber yoga mat. Cut a pc of the mat and held it against the leak with the magnet. So far the leak stopped. Can't wait to convert to gas!
