3M Lightweight Body Filler, 05800, 1 qt, White, Repairs Dents, Dings for Automotive

Awesome stuff! I would recommend using an epoxy primer over it, but of course that’s with any filler.

As a paint & body man this is some of the best mud you can use, top qualityWon’t be disappointed

Smoothed out nicely

I think activator is too small, so try to measure really well cuz if you run out of activator the putty is useless.

I followed the directions and used it to make a repair to my sailboat, it was easy to work with and worked great. Became rock solid and sandable in the expected amount of time and seems to be super strong and lightweight.

Filler arrived without hardener. Amazon says contact 3M. 3M says it wasn't ordered from them (which I knew but tried anyway on Amazon's suggestion. Contacted the distributor who shipped the product and got a run around with no results. Probably a good product but don't order it here.

you know what this is and you know what it does, im here to say it still is the best "bondo" in my opinion, also It does come with a tube of hardener, its just not shown in pictures, and rather its just haphazardly taped to the can...

It's an OK filler I did have a lot of problems with pinholes and I've been doing this for 20+ years and have noticed it's becoming more common in almost every filler no matter the brand but they have stuff for that too.
