I am looking for something to help some older slightly rusted exhaust pipes underneath my truck, after cleaning the rust will this be ok to use?

I think if you prep it and followed the curing directions you would be ok. I used it on my new Hedman headers, but I used their primer also. So far so good. Hope this helps some. Good Luck and God Bless!

It should be. I used it on Harley exhaust with no issues. Those get hotter than truckexhaust. Just follow the instructions to the letter.

Not sure what you are using it for, but if your planning on doing a permanent long term repair I would replace the metal. Por has been a big pain in the butt for me. I'm running into problems using it to restore a car right now. I wish I never used any of their products to be honest with you. That said if you are making a temporary repair it sticks to sand blasted or rusted metal. Scrape the flaky rust off and clean it with a wire wheel use there metal clean and apply. Granted there is a place and time for por15 but it's very hard to top coat and takes a long time for all the processes to be completed. There support line is usually pretty informative though.

It should work just fine, as long as any rust hasn't caused pitting in the metal. But, for discoloration, it should work great.

After removing the fill pipe. I used a porta band saw to cut a section out of the fill. A hack saw might work, a saw zaw with a metal blade would work. The time to remove the tube complete is very important as you want to clean all metal shavings then reinstall. This will take a bit of time but your trucks worth it. So is the ability to not have to fill up every couple hundred miles. I now enjoy a thousand mile turn around on fill's. If I can help further, e-mail questions to dozer327@yahoo.com V/R

No, not unless the rust is removed, primed and then sprayed. I used it after sanding, a bonding, priming, matching the paint and then the clear coat. It might help over a fresh scrape. once there is rust, it has to be repaired. Hope that helps.

I've used it for holes on the mufflers and exhaust pipes on my 2 cars for over 5 years or so and it works great. If the hole is over 1/4 inch or so I use a piece of sheet metal and a pipe clamp to fasten over the sealant while it is still wet. Form the sheet metal to the shape of the pipe or muffler you are covering. Use a thin enough piece so that you can form it some before clamping it down, .02 to .03 inch thickness (1/32 inch thick or so). It has extended the need to replace the pipe or muffler for 2 to 5 years.

I would clean it with a Brillo pad, make sure it's rinsed good and then dry, and then protect the parts where the rust were with some car wax.

I just use some today, and you do have to rub it sometime to get the rust to come off. I have seen the metal turn black and some time metal gray when the rust was removed. I love this product, it just saved me some tools that had gotten wet and rusted badly. I thought I was going to have to throw them away but it saved them. Well worth what I spent when I saved my Harley Davidson gas tank that rusted inside when it sat to long.

I haven't seen any rust issues so far. Buying better hardware certainly won't hurt anything, but I would recommend using some type of thread lubricant to protect the exposed threads as you would in any other outdoor application.

Id try something else like Semi-Chrome or Noxon. This is more of a Polish than a rust remover / Chrome Cleaner. Although it may do the trick, you can try it but Id say to buy a can, only if you have other uses for it... this stuff lasts a good bit and works great for shining stuff up.

SHould work OK. Just make sure you have the correct adaptors to mount it to the exhaust pipe

I am no expert. But it seems to me that as long as your exhaust pipe is not 90 degrees - anywhere - and that the distance to outside is short & it is away from overhang, you're OK. ....

probably since it has a coating, but i would recomend using black pipe. it may be cheaper in the end and alot stonger. i would also paint the black pipe before installing it underground, first i would contact your local code enforcement burying this line may be illegal, witch is why i returned the gas line i bought it was illegal for me to fun it through a wall, i had to use black pipe and it was cheaper. lowes and home depot will thread the pipe almost to any size you need. and black pipe comes in 21 foot lengths.i paid about 30.00 for 1 21 foot length and i needed 3 plus all the fittings and pipe dope, cost was only about 200.00 for everything including paint for the pipe so it won't rust.

Yes just be sure the area is very clean and degreased. I am using it for my intake gasket and also for steam engine gaskets.

I don't think so. I used it on a gas tank on my motorcycle and it only took off the surface rust but not the think stuff. I soaked it for two days but no luck. Hope this helps you.

I'm assuming that you're wanting to repair an old rusted muffler and I think that this tape is designed to protect components from heat and not for repair. I have used it on the plastic belly pans on several snowmobiles that I have been rebuilding to reduce potential of heat damage from the exhaust. The tape is a foil with an adhesive backing and is used to reflect the radiant heat away from whatever you want to protect. I can't imagine that it would provide any appreciable amount of strength and the surface that you're applying it to needs to be clean and free from any oils or grease.
