Does this work on cracks in outdoor fountains?

Depends on the materials you’re fountain made of? Mine was concrete and I used JB WEILD that you have to mix 2 tubs together. One a hardener I believe for the other tube. Same stuff that sometimes is used on engines for repairs. Don’t get the new JB weild that you don’t need to mix causes it won’t work like the old original JB weild! I bought a used fountain and didn’t notice the cracks till after I got it home and filled it with water. Apparently last owner let water freeze in the fountain that badly cracked it. I put the JB weild over the inside and outside of the fountain over the crack on both sides. Been least 6 years ago since I sealed the crack and no problems at all with it leaking any more!

I’m wanting to remove the carpet in my Jeep commander and replace it with a spray rubber floor. Would this withstand being the floor in a Jeep?

I wouldn't use it for that. Spray on bed-liner would work better.

Can this be used on a cast iron pipe?

A very good Value for Spry Sealant Gorilla Waterproof Patch & Seal

The Spray Sealant comes in a very easy to use spray bottle. The application however comes out quickly and is not that easy to control the placement. This is just a normal nozzle that would be on a pint can. The nozzle has the problem of getting "gunked up", so have a rag or something to clean it. you will have to continually shake the can. Thus I suggest that you ensure the area or thing that you are going to spray is prepared. Overspray is definitely an issue as well. . It dries in very quick time. About 4 hours. The directions give you a specific time for full drying time and curing. Be aware that the Sealant is not "clear" It will leave a dark "plastic" covering to the wood and or product that you are trying to seal. The clean up of the sealant was NOT easy and quick. The Sealant strength was impressive and very strong. I used multiple bottles and the product melded together seamlessly. The amount of Sealant that you require is more than you would think. A little does not goes a long way. I used it on my roof, and it rained the next day. I used it and it worked perfectly, the water resistance was outstanding. An excellent value, use and overall Adhesion. I would defiantly recommend this product and I would purchase it again if I needed more.
