As far as how much to use, it depends on the part you are making. For a [[Make a fiberglass fan shroud|fan shroud]] you can lay up two layers of mat over most of it and reinforce all the edges with a third layer. All 2 oz mat. This would give a very light weight body, a little less than 1/8" thick and stronger edges a little more than 1/8" thick. | As far as how much to use, it depends on the part you are making.

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].

| + | Reinforce edges as required with a strip of mat. You can also reinforce edges with woven tape, this puts many continuous unbroken filaments parallel with the edge of a part, and will make it much more resistant to cracking from the edge in. | ||
