Smooth-On XTC-3D®, Protective Coating for Smoothing 3D Printed Parts, 24 fl oz

If you love your print and want to give it a super smooth and shiny surface, USE THIS STUFF!!!Don't use this if you intend to paint your print afterwards. Fiberglass resin does a good job of smoothing and is MUCH cheaper.

If you're going to put some serious use into something that you want to look good, this stuff can deliver.Pros:- Tough- Won't wash off- Smooths out the plastic- Comes with disposable measuring cup, mixer and brush.- Dries quickly. You don't have to wait around forever for it to set.Cons:- You have to respect this stuff. It comes with a Material Safety Data Sheet. READ IT.- It does not wash off easily. Expect the measuring cup, brush and anything else you use while applying this stuff to be permanently covered in the resin. For me, this means disposable brushes, gloves, measuring cups and covering my work area in tin foil before I start.- Dries quickly. You can't waste time once you've mixed up a batch.- You have to use it correctly. It comes with specific instructions on how thickly it should be applied. A "just paint it on" approach will not guarantee the results you want.For someone who wants to make a good looking object that can take some abuse, this stuff will do great.For someone who wants a smooth, pretty object to put on a shelf or that you know you'll treat gently, consider something less toxic and easier to work with like: an acrylic gel http://www.amazon.com/Acrylic-Medium-Golden-Solid-Gloss/dp/B0007W5RAYYou'll still have to pay attention to get the results you want, but it doesn't require safety equipment and you can wash it off your brushes when you're done.

Worked great. Dries extremely quick. Mix only what you need. Goes way further than you think. I mixed 5 times too much the first time. A little goes a long way.

My go to when printing a model I want to look finished. Takes some time to get use to applying it right. A little goes a long way.

Used this on a PLA print to smooth lines. After two coats model was smooth and paint/primer stuck without issue.

I've used this stuff before, and it's great quality. When it's actually usable at least. I ordered this with Prime shipping, and it still took well over a full week to arrive even though it was only supposed to be 2 days. Then when it finally got here, BOTH bottles were completely ruined. Neither bottle had a seal on them, and both lids had come unscrewed, dumping well over a quarter of each bottle into the box and ruining absolutely everything. It was dripping when I opened it. Not only was there so much wasted material spilled out, but both bottles had been exposed to the air for god only knows how long. I live in an extremely humid area, so even though they refunded the order, I refuse to touch the remaining contents. Maybe I'll attempt to use it on something I don't care about ruining or not, but otherwise it's just trash. I haven't bothered to order another yet, because I had ordered it to use on an item I needed by a specific date, and since it took so long for it to show up only to find out it was ruined, there wasn't enough time to order more and have it arrive on time by then.That being said, again, the material itself works lovely, if you can actually use it. It fills 3d prints very well, is easily sanded with a nice finish, very strong, and can even be used as a glossy top coat depending on what you're making. It has an unpleasant odor, but the odor disappears once it's fully cured. A wonderful product for cosplay, props work, or eve just general use. But I would absolutely advise they start sealing the bottles if they don't normally already, because I'm not going to keep wasting over a week at a time waiting for the item to show up (despite paying with a prime membership and it swearing that it will only take 2 days) just to find out that the bottles got dumped out because they weren't sealed/had the lids on right.

Very easy to apply and sand.

Product was as advertized came very quick, pleased with product.
