| − | + | '''Balsa wood''', this is used in large flat areas and needs to be bedded in...not really a good choice but it is one of the oldest cores. Boatbuilders used it extensively for reinforcing large flat areas such as decks, hull bottoms and cabin roofs. | |
| − | Urethane foam..this comes in varying thicknesses, and is used much like balsawood. | + | '''Coremat''' is a material that looks similar to the absorbent paper shop rags that come in a roll, it's made with fiberglass and microballoons, along with a binder. It's mich more flexible than balsa, and it comes in several thicknesses, 3mm, 5mm, and 8mm..This you lay up into your part, just like another layer of matt or cloth, then put another layer of mat over the top. |

Use a core anywhere you have a large flat or gently curved area, roofs, hood tops, floorpans, bellypans. The underside of fenders above the tires is a good place to use coremat, as it will provide a cushion against stars from rocks being thrown up by the tires. | Use a core anywhere you have a large flat or gently curved area, roofs, hood tops, floorpans, bellypans.
