It turns out that the best way to cover the mold with wax paper is to dismantle it and wrap each part individually and then cover the plywood with wax paper and screw the pieces back down. That way you can get nice tight corners. I tried the other way of just covering each channel but the the inside corners are very hard and the wax paper is not very sturdy....

I laid the part up this afternoon and the wax paper worked out very well.
The only problems were do to the cutting of the material and the hardener content in the resin.
In my effort to get good glass coverage I cut the pieces just a little too big so there was "rollup" at the sides and some buildup at the joints. Nothing that can't be corrected with a grinder.
Most of the layups I do are only 2 or 3 layers of combomat or biax tape. So it goes pretty quickly and there is just a little heat buildup. But this was much thicker part with 4 layers of 24 oz Combomat and 1 layer of 4 mm core mat using about 3 gallons of resin and it generated a fair amount of heat which caused the last layer to set too fast and melted the bottom layer of wax paper onto the glass. But over all I am pleased
The inside came out very flat with just a few wrinkles to fill. I can fill and grind the outside to smooth it out. The thickness came out fine at about 7/16". Sure saved a lot of money in resin and cloth doing it this way. The numbers you see were marked on the pieces to keep track of where they went. There were 57 pieces total in the 5 layers. Onward!!!!
