Pros & Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

Much cheaper than a muffler shop. Sealed up the small crack in my exhaust right around the o2 sensor by manifold. Nothing lasts for ever on a firebox, but its a 10 minute job with great results.

J-b weld is my go to for this application. Press on the outer crust to help the j-b flow into the crack. Saved a couple hundred bucks using this instead of bringing it in for service.

Cons

Hairline cracks are common on the ecotec 4 cylinder motors. Applied jb weld and waited 24hrs to set. It’s gritty, not smooth and to thick and *.

The bbq never goes over 450*f. No full boost or high temps.

Highlights

The AI used to provide these results are constantly improving. These results might change.

Quality

Great for high heat repairs including engine bocks and cylinder heads of naturally aspirated engines

The strong adhesive power is impressive too it holds up well even under high temperature

With this product you are not just fixing you’re creating unbreakable bonds

It feels like having a superpower in a tiny jar ready to fix anything that dares to break

Price

Fixed my broken firelogs thereby saving me 200

Shipping

Delivering a performance as strong as its bond an absolute win

Update 3 weeks after the current review jb weld has contacted me and has made good with the product sold

Packaging/appearance

I opened up the container mixed it up and filled the hole in the aspirator pipe that was rusted through

Packaging could be better as it comes in a small whiter plastic jar and hard to mix unless you remove and stir up in a plastic bowl

Competitiveness

Bought this in place of the much more expensive labmetal brand and it worked very well
