Bondo Glazing and Spot Putty, Fills Pinholes, Scratches, Minor Dings & Hairline Cracks, 16 oz, 1 Tube

There's a great video on YT using this plus acetone to smooth 3D prints. It works great. Way faster than sanding bare filament. I print in black so the red of the putty makes it easy to see where your high points are.

Good product

I am about to buy more in case the winers cause the removal of this product. It's not more "toxic" than any other paint primer, solvent or filler. I get it on my fingers often and nothing happens! It does a great job filling dents, uneven surfaces and nail holes before painting. I haven't had ANY problems using any paint or primers after it completely dries. You can't apply any paints until it dries! It dries quickly (a plus), so if you work too long with it, you'll have to scrape your putty knife or applicator. Sands easily, scrapes off putty knives easily, but bonds securely to your job material. If the dent or hole is larger, plan on using multiple applications. I appreciate this product.

I use this to fill small imperfections in woodwork, trim, etc. prior to painting. Dries quickly. Easy to sand. Produces extremely smooth surfaces.

I have been using Bondo for two years now and I have to say it works like a charm. I mainly use mine to get rid of layer lines in my 3D prints and I have to say it works amazing. With One 16oz tube I was able to smooth down 15 big prints for my cosplays and every time the filling is amazing. I do recommend using it in a well-ventilated area due to the strong smell and use the proper PPE when applying it, sanding it, or being exposed to it. It is easy to wash if it touches the skin, I just wash it with warm water and soap and it does the trick.Overall, if you are looking to smooth out your 3D prints, this tube will last you for multiple projects.

I have been using it to fill and shape 3D print lines and fill in areas that have been slightly misshaped from support material. It works really well and sands smooth really easily. My only complaint would be the lack or working time. It seems to start drying up instantly and you have very little time to work with it. I have heard of people using acetone to thin it out and increase working time but I have not tried it yet.

Glazing putty is useful for smoothing out 3D prints that have a lot of lines in them. I've mixed up the 2 part versions, but sometimes having something you don't have to mix is nice. This stuff sets up within a few minutes, so you don't have a ton of working time, but if you work in small areas, it tends to work pretty well. This is a nice bulk size that will last a while, assuming it doesn't dry out. It sands well after curing, but a layer of primer over it is recommended before final painting.
