I have worked with this mold builder numerous times before also. I do not have the slow drying time issue as reported above. Here's a tip to cut drying time down in between each layer you apply. Use a hair dryer set to low heat and have it blow the warm air directly onto the part you want to dry. Saves a TON of time. I can build a mold in no time using this method. Just watch out for warping if the part you are making a mold of is very thin plastic. Hope this helps, I-am-Boba-Fett
Thanks for the tip. I like that. I tend to really smear the 3rd and 4th and 5th layers on kind of heavy, but with thin enough applications, it dries fast enough. I guess I should have said, "I leave it to dry for 6 hours, while I go do something else like watching water boil" ;-)
I'm sure to hear the Mrs complaining about her missing hair dryer.
