It is expensive, but it states that one (2) ounce piece will do "5" cars. That means the whole kit can do up to 15 cars with the 3 pieces it includes. That might be worth a look!
I have been using clay magic and mothers and can`t get more than 2-4 cars MAX out of 8 ounces. I am looking for some user opinions on how long the clay lasts compared to other brands. Is it some kind of new material?
