I've been laying up a few panels with 6oz and Poly resin, both by UV and with MEKP. I am not using a roller, just a squeegee and trying to use as little resin as possible just to wet out the cloth. I've had some of the panels start to warp a bit in the center when I release them from the glass.
Any ideas why I'm getting this warping? I have been laying up about 6 layers at a time and letting it cure, sometimes leaving it overnight, before continuing to add more layers to reach the final thickness. Is this the problem? Do I need to wet out the layers in small catalyzed batches continuously all in one sitting? Is it even possible to do this or would this cause a problem?
Any help would be greatly appreciated. Thanks.
