Is there something along the lines of a bondo type substance that i could ruff mold with my hands then let harden and then craft out with a knife? Say like to make a spoiler for a tf figure? Any sugestions?
Depending on how much sculpting you're planning to do in the future, you might want to think about picking up a batch of Apoxie Sculpt while you're at it, too. Fixit's better for super-fine details, and thin parts that you want to be made durable, but Apoxie's cheaper, so works better for bulkier, less fragile sculpts.
Though I only personally have experience with Fixit, this has always been my understanding as well. I just didn't want to recommend something I hadn't used.
Apoxie handles almost exactly the same as Fixit. It's just not as stiff right after mixing (wait maybe half-an-hour after mixing if your require a firmer material), so you need to be a bit more patient with it if you need to do some finer sculpt work.
TY everyone for the suggestions, when i get my shipments in the mail i will tell you guys how it turns out..
