[QUOTE="hihoslva, post: 270909, member: 548360"] Juse use straight-up fiberglass mat for the first layer or two (the mold). There is no need to mess around with fleece, cheesecloth, or any other material when making a mold, especially on the floorpan. Just lay down mat. If possible, do multiple layers all at once. There is no need to do one layer, then another, then another. By doing several layers at the same time, you make the cure and your mold that much stronger right away, reducing the risk of cracking it when pulling it out, as well as reducing the risk of heat warping it later on with more layers. It also becomes very easy to add layers, because the surface is nice and sticky. Fleece is only really necessary when making "free-form" shapes - to stretch the fleece from one surface to another and create a flowing shape on which to later lay fiberglass. For molding, go straight to glass - it's stronger, and one less step in the process. ~HH [/QUOTE]
