: Hi,
: Yesterday I made a box out of scrap plywood, filled it with cement and sat in
: it, creating a truly custom fit fiberglass seat. I have read other people
: have made seats in a similar fashion, but they make a cement mold, then
: then they use that to make a mold from which the seat is made. Why not
: just skip a step and use the cement mold to make the seat directly?

Oh, by the way... Cement? ? why cement.?
