    Seems like this might be the first post for some actual help in this thread for a while... Here is my question. I started to make a mold for a piece of a gun I'm working on and after building the containment field, pressing the piece down into some clay and pouring on the oomoo, I ran out before the gun was completely covered. My question is, can I pour more urethane rubber on top of it and just continue on like before even though the stuff that is on it now is already hard? Or will I have to make a new mold? Also, if I can just put more rubber on top, can I use a different kind? Like silicon RTV tubes from Lowes or something? Thanks in advance.

    I have never used any mold making materials nor have I ever casted anything. However, I plan to. I always do TONS of research before I do anything so let me see if I can remember...

    I believe you can pour more urethane rubber on within a 24 hour time period (I THINK) It may be less, or longer. Urethane and Silicon do NOT mix. Therefore, it will not bond at all. If you pour Urethane inside a Silicon mold, you dont have to use a release agent (although it is recommended)

    Because it is so expensive, I'd go ahead and try adding more urethane. Urethane bonds to Urethane. Silicon bonds to Silicon.
    Hope this helps and I hope I'm not too late in helping!


    I have my own question. Will Urethane PLASTIC bond to Urethane RUBBER? Or would it be fine with a release agent (Vaseline / cooking oil spray)

    If you're not trying your best, don't try at all.

  9. I'm not sure where to ask this, but casting seems like the most apt description of what I'd like to do.

    I made a pep Daedric dagger (from Skyrim) and I would like to fill it with something to make it more solid. I am thinking about filling it with expanding foam (carefully), but it seems like it wouldn't feel heavy enough, and the expanding sounds dangerous.
    So, any other recommendations? Also, would this belong better in another help forum? I am new to this, as well as 405th.

    Thanks for any help you can give!
