Pros & Cons

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

Pros

Follow the directions precisely and allow more time to cure than the recommended time. Within 10 minutes it was cured and solid. Put a vacuum on the system to help pull it into the hole a bit.

Needed to repair plastic faring bracket in motorcycle. Used jb plastic putty and plastic glue on other repair.

It works, but. It works, if done correctly. It sets super quick.

Cons

It starts hardening within a minute. Allowed to cure overnight, leaked immediately. It needs a better warning or better directions. This product is only for temporary fixes of your radiator.

Horrible product. Cannot recommend for use on radiators. This is not mentioned anywhere on the packaging.

00 after shipping and all the other add ons

Packaging/appearance

This gave me time to wipe off the package corner and fold it over a couple times to seal it

I still have half of the epoxy left unused in the bags

Then i applied the fiberglass mesh lightly pushing it into the epoxy

Competitiveness

But other than that it’s been holding up perfectly for the past 3 weeks on my bmw e92 lci

In the past i used standard jb on top of a brass radiator and it held for more than a year until i sold the heavyduty truck
