Reviewers highlight its fast curing, smooth sandability, and ability to create hard, long-lasting finishes on wood, metal, and various surfaces. Many appreciate its ease of mixing and application when the correct hardener ratio is used, with repairs often becoming virtually invisible after painting. However, several customers express frustration with unclear mixing instructions and inadequate printed guidance on the can. A few report issues with underfilled containers, strong odor, and improper mixing causing slow curing. Despite these drawbacks, most consider it a reliable, effective repair solution.

I restored a 1968 Dodge van in 1992. It had been in a front end collision. We were unable to push or hammer the metal out to the original position so we sanded down to bare metal and coated it with several layers of Bondo. My friend who helped me said it would hold for a while but would not be permanent. Well it is still there and I still drive it regularly, mostly in summer but most people who see it don’t know it is there. Thank you for a great product.

Not just for Auto Repair
Would RecommendExcellent product for so many other applications. I use it to repair metal, wood, plastic, laminate and ceramic. Takes practice to keep it smooth otherwise it requires a lot of sanding.

Brilliant, it works!!
Would RecommendA painter friend of mine turned me on to this product while we were painting the exterior of a home. Parts of the exterior siding were basically rotted away at the bottom. I dug it back until hard wood, cleaned the area thoroughly then mixed it up and started filling. AMAZING! Solid as a rock. It took a few fills because it hardens so quickly. (90* outside). But, seriously, I wore gloves and uses the side of a paint stick. You couldn’t even tell there was ever a problem. Customer tips us $400!...

Instruction Sheet is too Small
They have a whole can to print the usage instructions on. No said the layers, we need that for the legal disclaimers. The instructions end up on small piece of paper, in the smallest font possible. This is why people hate lawyers.

Unfullfilled
Would RecommendBought a new gallon can of Bondo Filler and opened it to find it was only 3/4 full. Is this normal? Great product but disappointed in this aspect!
