It’s easy to apply, dries quickly, and finishes smoothly. The green color is helpful for seeing application.

For everyone in the auto world that is about to say "Well no @$%# ya moron". I am a Hobbyist. I got this from a recommendation for filling seam and layer lines on 3d prints. This is by far the best gap filler I have found so far.Pros:-Goes on super smooth-Dries lightning fast ( Work in really small amounts )- A little goes a very long way.Cons:-Dries Lightning fast. I got to the point where I was applying little dabs from the tube directly onto the piece in working on, No time to put it on a different surface.- This stuff is toxic

Really good for the price. Isn't the best but it's good. Really good stuff I buy is a little more and harder to get lately. This has been a cheaper alternative still being a good product.

This material creates an extremely hard smooth finish. We have Austin sculptures that have broken in shipping and I use this material to fill in missing spots where the concrete material was missing. When sanded and painted, the breaks or chips are completely gone. This is like a wonder material. It dries quickly and sands down really smooth. It can also be used to build up areas.

Love this stuff. Love that 3M makes green and white in addition to the red stuff. I use this for actual auto body work and more recently with some 3D print projects. I think a lot of the bad reviews coming from the 3D printer crowd is because they don't understand the purpose and nature of this product. It's a post bondo, primer spot putty for glazing over scratches and pin holes. If you try and cover a large or deep area with it there is a good chance it will glaze over faster than you can work it over the area you're trying to cover. If you've ever worked with this type of product in a body shop environment you'd know that the user is intended to squeeze out about as much material as you would when applying toothpaste to a toothbrush then immediately thinly knifing it over a small scratch or pinhole in your bodywork. Whether you use this for 3D prints or actual automotive paint-prep it behaves exactly as designed.

I bought this to fill the gaps on my Scout Trooper helmets. I used the red Bondo too and I have to say I like this better because:1. This is much less smelly, though a respirator is still a must.2. It seems to sand smoother than the red tube bondo.3. It it resistant and firm when cured.I've used it in the initial fill and then at each other step when wet sanding would reveal a small nick or something.If you are going to make and assemble 3d printed models, you need this... you will love it too.

I use this product to fill and smooth my PLA 3D prints and I think this is the best product I have used! I have tried other things such as XTC-3D, bondo, etc but this is probably the smoothest product I have found. It dries VERY fast (20min-ish) which is perfect for getting my products out quickly and efficiently. I usually do about 2 layers depending on the quality I print at. I sand it at about 400-800 grit and then spray filler primer and get a beautiful smooth finish. I do recommend a mask and applying this product in a well ventilated area since the smell is strong and lingers for a bit. Other than that, awesome product!
