    Please help. If I made a mold of a product and didnt have enough material can I add more silicone after the bottom half is cured? My mold only filled about half of what I need and the store i buy from is closed.

    you're in luck...silicone only sticks to silicone...so you can buy some more and pour it in and it will work out fine.

    Absolutely you can and in fact I had to do that (part fill the mold box) to make these molds.

    The part fill was to allow finger pull holes to be created in order to separate the parts. It also saved silicone :)

    Yes, you can, as long as the surface you are pouring it onto is clean of dust and oil. If the piece will be under high stress during piece removal, you may encounter some delaminating if there were impurities between the two pours.
