After covering the seams where the flanges meet each other, i went along the edges of the lip to fill all the cracks to make a smooth transition. I would have had to order filleting wax so i started with Plasticine then switched to wax from a wax ring seal for a toilet.



once that was dont i sprayed a coating of PVA mold release agent on the lip. I did one coat but i really should have did two. One tack coat and then a thicker coat. Some PVA can be brushed on, but i used a LPHV (Low Pressure High Volume) sprayer. Once the PVA was dry (green tinge) i started coating it with Mold Release Wax. i did about 4 coats, i think i might do one more before it start the Tooling Gel Coat layer.

Before i brush on the Tooling coat, i will take my fiberglass cloth for building up the mold and cut pieces shaped like the mold. i will do this before to save time. For videos to help learn about this process check out Youtube channels by Easy Composites and Matthieu Libeert. Both very helpful.
