Questions & Answers

Can you tell me how long the tape is?

The length of the ship is 3 feet, 6 inches

For this to bond, how hot do I need it to get? What can be done with a couple hair dryers and a lighter?

Although, in my opinion, this product would not be suitable to use on hair dryers or lighters, if you are planning to use it on mufflers or exhaust pipes, you may want to run your engine for a few minutes first. In order to apply it to a warm area, not a very hot one. That way, you don't have to worry about skin irritation.

What if I want to use this on the flex section of a front pipe?

There is a chance it will. Let's make sure that we clean the pipes really well. A trial of the product is possible due to its low cost.

How do you remove the silver lining piece? Do you peel it off or does it come with the whole thing wrapped up? When I opened mine, I discovered that there were two distinct pieces. ?

Hello, The packaging of this product puts the silver on the outside and the sticky part on the other, so the silver is just the part that sticks to the outside.

This is a challenging task to get rid of the red outer layers! Despite the fact that my exhaust system was otherwise in great shape, I had to use some of these bandages to patch a hole in my 2009 Mitsubishi Outlander 4cyl exhaust system

5/5

This bandage has a major drawback because you have to peel off the red coating on BOTH sides of it, not just one side. Though it is very difficult to get it started, there is a trick I discovered that might With a lighter or torch, you light one corner until you see the red coating has gone (on BOTH sides), then both sides can easily be peeled off. Each bandage will take you a half hour to pull out if you try and pick at it. The experience has been The epoxy bandage under the red coatings, however, is heat resistant, while the red coatings are not. This is why we need to try this little trick to begin the procedure. Afterward, the bandage seemed to work well, and it is still holding up after several days!.

I wouldn't spend the money on this

3/5

Among all the Permatex products, I figured it was a slam-dunk. I definitely will not be doing this one. First, the instructions direct you to "peel off the backing of the bandage. " Seriously? We spent close to 15 minutes picking away at the product before we could open it. There are no easy-to-see edges or slits to enable us to do that. Afterward, the stuff did not bond well to the exhaust pipe it baked and became rigid, but it did not bond My life will never be the same again.

Since it's sticky when applied, it can be a bit messy to work with

5/5

However, if you are going to attempt this, you already know what you are getting into in that respect. You can be confident the repaired section of the pipe will be as strong as the entire pipe. In addition to the cement, it took probably about an hour to fix.

It is best used when combined (a must) with Permatex putty

5/5

* Before applying, you will need to wire brush the affected area or sand the area to be repaired. After that (THE SECRET), degrease this area with Acetone, carb cleaner, etc. (Cold engine and pipes, don't blow your car up! Usually the wire brushes have some oil or grease on them that makes the putty unstable. Put the putty on and make the area pretty with a putty knife, then cover the area with tape while the putty is Keeping the tape smooth will make it work better if you wrap it all the way around and overlap it a bit. If you do it right, the patch will outlast the rest of the exhaust system if it is left over night. After it has sat for two hours, start the car and let it idle for ten minutes before turning it off.

I didn't even last a A small leak was covered up in my exhaust system, and it could not last 12 miles down the road before it broke and fell

We tried two times to cover a 1/2 to 3/4 inch hole

3/5

This item has been ordered twice in order to cover a 1/2 inch to 3/4 inch hole in my Jeep Grand Cherokee pipe. Both orders have been successful. In my 2nd attempt, I wrapped it several times directly over the hole. My best guess would be that it burned through within an hour or two. It may be too much for this tape to handle a hole that big.

This worked for me, however it was less durable than I had hoped

4/5

The text has been modified. This worked for me, however it was less durable than I had hoped. After about a week, it faded off. Luckily, I just needed to pass an inspection within a few days! Honestly, I suspect the failure was partly due to the proximity to the cat. A 10 inch section of it was used upstream of.

It's a great fix for the short term

4/5

There was a small hole in the pipe between the two ends of the hose for a few weeks This muffler and pipe are for exhaust purposes only. For a temporary solution, I think it is good, but I think it will not last for There is a film on BOTH sides of this tape that you have to remove, but the instructions are not very clear.
