A body part would need a couple layers of 2oz mat, a layer of 1.5oz plain weave cloth and possibly a third layer of mat, depending on size. Again, reinforce edges as required with a strip of mat. | A body part would need a couple layers of 2oz mat, a layer of 1.5oz plain weave cloth and possibly a third layer of mat, depending on size.

| − | For one example, see [http://www.hotrodders.com/forum/journal.php?action=view&journalid=2439&page=25&perpage=5&reverse= this journal entry from Willys36]. It's a shell for the headliner of a '53 Chevy pickup, and used only 2 layers of mat (about 3/32" thick) for light weight and flexibility. It is more than strong enough. This is also an example of a part made from a female mold, but without the gel coat since it is covered with upholstery and doesn't need a paintable finish. | + | For one example, see [http://www.hotrodders.com/forum/journal.php?action=view&journalid=2439&page=25&perpage=5&reverse= this journal entry from Willys36].
