Mluvara, first off that’s for replying to my thread on glassing over foam wings and pointing me to this thread. I am sure many will get a better understanding from your posts. I run a Model Shop for Industrial Design Product Development and I just finished 3 molds for my 25% Edge 540 and I have some questions for you. Why do you prefer to add primer to the mold before laying up parts? It’s the same amount of work as spraying the body? Are you spraying this over the wax parting or over PVA? Can you describe your splitter plate please? When I CNC machine my plugs I cut them in halves (very easy with CNC) and when you lay-up the first mold half you have a flat parting line? I have never tried the glass stabilizer before but I like it. Do you add any ribs or foam to the inside? I usually vacuum-bag over foam for this. Thanks again.
