Takes a long time to cure.

I've seen others give negative review of this product due to incorrect use related to using the silicone with 3D Printed models. For FDM printers, the silicone will do a great job, no extra work needed. For resin printed 3D objects, extra care has to be taken to prep the models for use with the silicone. Most importantly, you need to properly wash the model with isopropyl alcohool. You can not use any isopropyl alchohol that you've previously used to clean other prints. If you do, your molds will come out a guey mess like others using the product have noted. Use isopropyl alcohol that you've never used before to clean the resin print. Once washed, spray it properly with more alcohol. The key here is to have no leftover resin on the model - if this uncured resin (invisible to see) comes in contact with the silicone it will contaminate it and the silicone will never harden and the contact surfaces will be a guey mess. Once you've properly washed the printed resin model with alcohol, wash the model with hot water and dishwashing liquid (not in a dishwasher), using a toothbrush to get rid of all the alcohol. Then rinse the model with water so that there is no dishwashing liquid (or alcohol or resin) left on the model. Put the model in water and cure with UV light for at least 20 minutes. Keep the model in the water for a day (preferably under direct sunlight - while still in the water). Once done, let it dry properly - do not use a hair dryer for this. Blow air on it or let it dry naturally, you can also dry with a cloth or paper towel. Only once it has completely dried is it ready for use with the silicone. Hope this helps someone.
