Default Magic Tape repair for plumbing

I had a slightly leaky pipe under my sink. I used a product called Magic Wrap to seal it. Magic Wrap is a non-adhesive rubber tape which tightly bonds to the pipe when stretched around it. This product seemed to do the trick, but should I be concerned with corrosion, since moisture is trapped underneath the tape?

Edit: Title should read, Magic Wrap, not Magic Tape

Why not just fix it the right way first and not rely on a "temporary repair"?

Any use of tape and such is a temporary measure that can last a few hours or even days, but you still need to take care of the pipe. I am assuming that it's a drain pipe you repaired (?). If the pipe is in good condition, it's possible that one of the threaded joints by the trap or somewhere else is loose, but if any portion of the drain line has rusted through, you need to replace it.

I just replace the entire drain line from the connection under the sink to the wall. The parts should cost around $30.00 at most stores in town, and you can go with plastic or metal.

I've used the stuff on connections between black poly pipe and PVC, where the hose clamp just wasn't completely doing the job. In such a case, it is a permanent repair. On a metal pipe that is corroded through enough to need the tape, that corrosion will continue and the pipe need replacing soon.

The issue I see is most leaks I have experienced are at a coupling, joint, etc. They are rarely (as in never) in a straight pipe run as those products show.

In a straight pipe run, a piece of rubber and a hose clamp would work....been there....done that....and it worked just fine.

If the pipe is corroded through or has a hole, no tape found in our universe can be a permanent repair. What tape allows you to do is to create a temporary repair, just like you can do with the muffler pipes of your car on the road, except that in this case you have to use another type of tape. Joins loosen-up and leak, and these can be repaired by either replacing the seal (s) or re-tightening. But any leak on a pipe means that there is a crack or hole on it. In this case a permanent repair is done by replacing the pipe, or by installing a pressure clamp designed for this purpose. But if the pipe is corroded in the inside area, not even a clamp will work.

I used a similar tape for military aircraft repair for years to repair wire bundles during emergencies, and then fly the aircraft to another location where we could repair it properly. Back in the Vietnam years we called this type of tape "F-4 tape," and I imagine that these days it comes with all types of names and colors straight from China.

It would help if you said what kind of pipe (water supply, cold or hot, or drain) and the material the pipe is made out of.

I would be reluctant to trust this sort of product to keep the pipe from leaking over a period of years.

Probably replacing the pipe is the best way to do the repair, it's not rocket science. Although part of rocket science definitely involves pipes that don't leak.

Thanks for the replies, all. A buddy is going to help me replace the pipe because I'm not good with wrenches.. lol. The Magic Wrap has been holding tight for 3 weeks now. No water dropping at all. The guy who suggested this product has had it on his pipes for a year with no problems. But his pipes are plastic, and mine are metal.
