I love Oomoo, I love Oomoo, I love Oomoo! Ok, seriously, this is much better than the Oomoo 25 I've been using as it has a much longer pot life, and it does cure harder also. This RTV is perfect for my mold making! :D If you have any interest in making your own molds, for candles, resin, jewelry, sculpture, anything, try it, you so won't be dissapointed!

Product is amazing!!! Exactly as advertised and simple to use. However... be aware that in shipping contents can leak from bottles and the 1 to 1 ratio is no longer feasible. Trying to get the order replaced was unsuccessful.

Rated by: Barry G. in Marietta, GA

I really like the amount of detail that is picked up no matter how small. Compared to other similar rubbers it is a bit too thick for my taste making it more difficult and time consuming to mix. Another problem I have is the softness which is good and bad-good for box molds -bad for two piece or even one cut box molds(it won't stretch much without tearing). All in all though it is a good product I would recommend it for simple mold purposes.

I have bought this the oomoo 30 and it just gets the detail done very well. It is easy to use and you can make a mold of anything simple a + b mix of equal amounts. Tear strength is okay so just ensure your mold has enough rubber to stay together well. I try to cut corners and get the most out of the product and have pushed the mold to the limit great stuff

Rated by: Cheryl W. in Brookfield, WI

This silocone rubber has exceeded my expectations for making durable, precise molds. I'm amazed at how perfectly it reproduces the tiniest of details. It's a little pricey, but does make excellent molds. I wish it came in the larger gallon size as one of these "starter kits" will only get me through one project. As always, MisterArt.com service and delivery is first-rate.

Phenomenally easy to use!! The one to one mixture was very easy to get; no guessing. And it made a surprisingly strong silicone. Great product! GREAT price!

Rated by: Garrett O. in Aliso Viejo, CA

If you are debating on getting OOMOO 25 or OOMOO 30, definitely get OOMOO 30! Its far more durable and easy to work with. Excellent product for making even complex 2 part molds. 1:1 mix ratio is the easiest I've ever used, and the rubber is fantastic. Highly recommended.

Rated by: Matt A. in Arlington, VA

Great stuff, it picks up the detail very well, I don't have a problem with air bubbles because they are in the mold and not the parts where the model is, so there aren't any bumps when I pour in the liquid plastic compound. Great product, keep it up, will order from you in the future!

Rated by: Tawnya P. in Memphis, TN

This is the best mold maker I have found by far! I have ordered multiple times & I am NEVER let down! This will get the smallest of details down to the letter & my kids (4 of them) love to use this for projects as well! So very easy to use!

one of the most detailed making mold i had ever dealt in my life A+++++++++
