The plan is to make one up from the top of the screen, rather than trying to take a mould off Rob's one (for now, anyway) which from memory didn't look like it could be taken from a one-piece female mould though I could be wrong.
I reached that conclusion because my car has a push on rubber seal running up and over the rear edge of the screen. I don't know if any of the other cars have this seal but rather than faff about finding out I figured I'd just take a mould from the top of my screen with the seal in place and then it'd definitely fit, and if anyone else has the same seal, it'd fit theirs too.
So, out came the masking tape, stuck the seal down as tight as possible and covered everything in the stuff to avoid any nasty residue from the parcel tape which was laid down on top to provide a smooth surface to lay up onto. Resin won't stick to it, so it's a nice cheap solution.
Something like five layers of 450g/m2 biaxial glass and a good slop of vinylester resin. Then some rather crude bits of bamboo cane wrapped in parcel tape and clamped down with a bit more masking tape to consolidate then layup into the dip.
Just pulled it off and it's looking remarkably good for something of a rush job. Tomorrow when it's properly cured I'll make up the outer part over some kind of former. Haven't quite decided how best to tackle that yet. The whole lot will get stiffened up as needed with some inserts or another few layers of glass once the outer's done.
The whole thing needs trimming correctly and filling/fairing to get it even and give more shape to the ends.
