what kind of plaster mold would be good for body casting .something i can buy over the counter and not have to order?
 
Do not...I repeat DO NOT use plater or gypsum to mold directly onto skin, well you can if you want to end up in accident and emergency....If you're on a budget I'd go for a slow set alginate....preferably with a number of people ther to help you out so you get good coverage quick....Don't forget to give your subject a rub down with petroleum jelly or cold cream as this will not allow the hairs on their body to become entrenched in the alginate mold.....Once the alginate is set use plaster bandages to make a mother mold....If you're ona tighter budget use plaster impregnated bandages...the medical kind not the hobby variety....These are meant for use next to the skin....But I still reccomend using smearing petroleum jelly on the body parts being cast.....Once it's set you can use mold release on the inside and then use fibreglass to make a light weight body cat from the two halves of the mold....

persoanlly though if this is your first project like this you're probably best off making a duct tape dummy....It's simple and very cheap....but still extremely effective....I used to have two, one filled with expanding foam that had a rigid internal skeltone to sculpt on and a flexible on stuffed with upholstery foam to put the finished suits on for painting and final quality checks. Hope this helps out.
 
You absolutly can apply plaster bandages right onto the skin just make shure you coat any hairs with vasaline. If you look in the winston effect book that how they did the lifecast of Kevin Peter Hall. There is no alginate under the plaster bandages. I have spoke to several people in the effcts buisnessa that do lifecasts and said they just use plaster bandages its a much cheaper route and the amount the plaster bandages heat up is not enough to cause discomfort and they come off rather quickly.
 
I am going to cover my ductape dummy with plastic wrap then with the fiberglass. Cut the fiberglass copy of the ductape dummy, repair the dummy as needed, and then I have a soft dummy for fitting and a hard copy to sculpt on. At least thats the plan. Fingers crossed.
 
Fiberglass resin may melt the thin plastic wrap. I would experiment with it first.

As for body casting, unless you have the money or need for skin detail I wouldn't do alginate. Straight plaster bandage will be just fine.
I personally did mine with ultracal and burlap(I know people say not to) I didn't have any heat build up,no burning or anything bad. Like Ink said, it will be thin enough to where it doesn't generate the heat like it does with a mold.
I used plastic wrap and wrapped my whole body first, you can also get a leotard and coat it with oil or vaseline.
 
God this brings back memories of a bowl of cold alginate and a topless girl I know bless her, she was so willing to please me.
