Worked great!

I needed to fill a rusted out hatchback of a 2010 Escape and this worked perfect. First we treated with the other steps to prep the rust and sealed it and then we packed the hole a bit and used NuMetal on top. Easy to work and smooth. My husband mixed the two parts and I made a snake shape and formed it on. We pained on top with factory paint. We aren’t professionals so it looks a little messy but better than a gaping rust hole!

Solid products

I'm not a body or paint guy. I've been turning tools in industrial applications for 25 years, so I'm not completely inept either. I opted out of fiberglass to treat rust on my 69 C10. I grinded back the rust and exposed healthy bare metal around the area to apply this epoxy. This product better than treating with fiberglass, I'm regretting not using this previously where I have already applied fiberglass. It has a great finish when sanded. It is a great shade of white when dry. Then I used their rust seal epoxy over this puddy and it looks great. Shipping was fast and correct, which most companies are failing at post covid.

Worse than jb weld

Jb weld stopped a crack on an aluminum fuel tank for 1.5 years. This junk lasted 1.5 days before it cracked and leaked. Im sure this review will be deleted. $75 wasted.

Amazing Product

I was skeptical at first about using this product to repair a gas tank that had many pin holes down the side. Boy was I wrong, it worked great! I think the trick was to do it in small batches as it was easier to mix and do a few holes at a time rather than the 10+ i needed to cover. Hopefully it lasts as long as it is advertised for! Held up through sanding and primer spraying too.

I wish I had this stuff 30 years ago! It's easy to shape and work with. I've learned that if you reinforce a joint and make it look like a 1/4 welding bead and then coat it with one of your products, it looks very professional. Awesome stuff. Will be ordering more in the future.

Excellent for minor rust repairs on body panels.

Had purchased to restore a cracked steering wheel but was working on 37 Ford body with small rust pin holes in difficult area to replace metal panel. Cleaned rust and applied epoxy. Adhered and dried prefect. A little sanding and pin holes fixed. Much better than bondo.

perfect patch

I am working on Old Chevy truck. Had lots of pin hole areas around windshield, cab corners, dash. Cleaned and sanded areas, applied rust blast. then applied rust seal and filled with KBS epoxy putty. Let it harden sanded smooth then did regular body work were needed and primed. If you have thin metal that you don't want o weld in new piece or can't because of location this is the stuff.

Appears to have done the job.

I used this to plug a pinhole in a motorcycle gas tank that remained after using the KBS Coating system on the interior.(For the record, the pinhole was not the fault of the coating system or its application.) The bike has been full of gas now for more than a month and the NuMetal is holding firm. However, the bike has been ridden very little due to other work I'm doing on it. If it continues to hold after a month of riding, I'd give the product five stars.

Excellent product and service

This product was so easy to use. I'm not too experienced with doing body work on my truck but even I had no problem using this product. The area I had to fill was a small crack and this putty was perfect for the job. I had plenty of time to work the putty in to this small space and was able to clean up the excess with soap and water. Will definitely be coming to KBS for future needs.
