Holts Gun Gum Paste 200g

I’ve used JB weld and pretty much everything that is used for exhaust repair and it all fails and breaks down. This has fiberglass in it making way stronger and keeps a nice tight air seal. I recommend this to anyone having exhaust issues. I’m using it to seal manifold gaskets since I don’t want to tap all these broke bolts yet. Works great, it’s a must have.

Great product. I use this water-based product for patching small exhaust leaks on my mufflers. It is easy to apply and I have used a heat gun to dry the patch enough to use within an hour to drive the car home from my DIY garage. If it dries out you can reconstitute it by adding a little water to restore it to pasty consistency. I have used this several times . Definitely recommend. It saved me from spending 600 on a set of mufflers that just had small quarter sized hole.

This product worked very well.

Wow wow wow!!! Had a bad broken exhaust pipe that was snapped in two, my car sounded like a total fart cannon. Used this stuff along with flexi-wrap. Amazing! Car sounds just like it used to! No more loud noise, exhaust leakage, loss in fuel economy, or foul exhaust odor!! Let it fully harden before you run engine above idle or 1000 rpms. Any bad review here is by someone who didn’t properly apply it or a mechanic who knows this stuff makes them lose money ! Lol the mechanic would’ve wanted at least $1000 for this fix here in Canada. They can take a hike! This stuff is great and I highly recommend it.

I received this fast I needed it because I had to repair some weather shoes for an affair, and it works perfectly

Man!!! Is this stuff great! Fixed an exhaust leak that nothing else could!

works good

Amazing stuff that will seal an exhaust leak. Fairly easy to work with along with the Holt exhaust bandage/tape.
