LET'S RESINPolyurethane Resin, 60oz 2 Part Casting Resin, Fast Cured Resin within 10 Minutes, Ultra Low Viscosity & Low Odor Pourable Liquid Plastic for Casting Models, Prototypes & Other Resin Craft

My first try at using resin and the result was beautiful.

My first time ever trying resin. Worked great!

If you want pure plastic this is your option. I liked the fact that the replica was great-but I had difficulty in hand painting it. It is expensive. Very short acting resin. Before I could pour it it was drying and thick. Turns white so coloring it before mixture pour may be the way to go. I would not buy it again. I used it because i poured a Plaster of Paris figurine and it was heavy and thought that my canvas wouldn't be able to handle the weight. A better option was buying a wood canvas/wood glue.

Wonderful quick cure resin but not happy with the way it pours from bottles. Very messy pour.

PROS:* Generous amount of resin for the price (60 oz compared to the standard 16 or 32). This is it's primary selling point.* Actual setup time is 4+ minutes, which gives you plenty of time to mix it, pour and adjust.* Nice and hard when it cures, and no odor once cured.* Easy to mix, easy to pour* The resin is thin (low viscosity) when just mixed, which helps it fill in holes and cracks better and more quickly.CONS:* Instructions warn that it is caustic. Wear nitrile gloves (included) and eye protection when using. If you get it on your skin it will likely itch or burn (ask me how I know). ;D* Oh, the smell. This puts off a noxious, chemical stench while curing (see Advice below). SMELLS BAD.* No easy-pour spout. I put mine in plastic "catsup" pour bottles to make it easier to pour. This may seem like a small issue, but the lack of a small spout (or at least a glued-on covering so we can punch a hole to pour) is a big deal when trying to measure small amounts.* Instructions say to stir for 15 seconds, but like other resins it requires a good 40-45 seconds stirring or it won't set up properly. (See below.)* Curing time to handling is about 30 minutes to de-mold (during which time it has a very noxious odor). For my projects that is no problem.* Initially it is crystal clear, but tends to form micro-bubbles as it cures. But since it dries opaque white, this isn't as big an issue as if it were clear resin.ADVICE:Odor: I recommend covering the curing item with a clear plastic pan or cup (I use playing cards), because the stench is really bad (will cause headaches with some people). Once it is fully cured it is odor-free, but during the curing phase it's really noxious. Several customers mention the odor-- and they are not wrong. Alternately, use in a well-ventilated shop area. (The smell will travel everywhere.) You can use inside your home if you cover the item while curing. That's what I finally did, and it worked well. Problem is you usually want to watch it for bubbles until it starts turning white (then you can cover it). So the smell can definitely be an issue.Actual Mixing Time: The advised '15 second' mix time is definitely insufficient-- and likely the reason some 1-star reviews find the stuff not setting up. This is a case of 'do not follow the instructions'. You actually have a good 3 to 4 minutes+ of working time (considerably longer than 2 minutes). You need to mix this stuff for 40 to 45 seconds. It is properly mixed when the entire fluid is crystal clear with no visible 'waves' or fog. If it starts getting warm, time to stop mixing and start pouring... but even then you'll still have around 2 minutes before it starts setting up.If you don't mix it long enough, it won't set up properly. That's a given for all resins. 15 seconds simply is not nearly enough time.Don't worry; you DO have time to pour after mixing. Pour large molds in separate-batch layers. Smaller items can be poured in one go. ONCE IT IS POURED leave it alone except for any bubbles that come to the top, which should be popped with a toothpick or sharp tool.POUR FROM A HEIGHT. Holding the mixing cup higher and pouring in a small stream will help de-gas as you are pouring into the mold. This is recommended by almost all resin companies and is the best method I know of for removing any rogue bubbles.VACUUM DE-GASSING IS NONSENSE. You don't have near enough time. So while the instructions recommend doing so, your vacuum chamber would have to be high quality and very fast or this stuff will set up before you have time to mold it. Consider: 45 seconds to mix, 30 to 60 seconds (minimum) to vacuum de-gas... how much mold time left? If you're Super Molder... go for it. Otherwise, forget vacuum degassing and just use the high-pouring method. Vacuum degassing is usually intended for longer set time resins.SUMMARY: This resin comes in a generous amount for the price (I wouldn't pay more), and it works. The smell (while curing) is noxious. It's a shame both liquids are clear as that makes mixing less user-friendly. But the final product is white, hard, has no-odor, and according to the manufacturer has no dangerous properties when cured (so it is basically just resin plastic and can be used for almost anything). I like it because of its low price. Once it's cured it is workable and paintable and works like any other resin product. It is only the curing stage that requires any special handling.As a note: ALWAYS WEAR EYE PROTECTION when using any resin product... or doing any shop work at all. Eyes are precious. Wearing gloves when using any chemical is a good idea. Many chemicals can be caustic or absorb into the skin and bloodstream. Best to be safe. Hope all this helps.

Works well. You have to be fast but gave a great white backing.

Easy to use, produces a good product.

This is the 3rd time I buy this. First time, I did several pieces, after 1 week, try to open bottle B and was impossible. Was less than half full, so I did a hole on the can and use all on several projects. The second time, I took special care on putting back the stopper on the bottle and clean everything with alcohol wipes. Because is hard to pour, spill very easily. But this time- I can't open the bottle from the beginning.... It's stuck, and the box was stain, so I assume some spill. I needed to do 1 piece for a present, so I did a hole again. The problem now is that the bottle is full. Not sure will be good in few days, plus is very messy to get it out. I don't think I will buy this again. I don't know how to contact this company to improve the delivery/bottle.
