Looks great AJ! Smoooooth....will reflect in the part!
Maybe you have already thought of this or have tested and it won't be a problem.....When we did glass off road car bumpers, we also broke the mold in the middle for release, like you did. However, we built a truss structure to keep the molds perfectly straight, i.e. didn't rely just on the flange to support the mold from flexing. Since you're going to bag it, I wonder if your mold might flex, even if just a little and your bumper wouldn't be dead straight?
My thought would be to bolt the mold together and if you can make it move even a little, I would clamp it down to something while it was perfectly straight and then laminate a truss structure to the mold. Of course the truss would have to also bolt together in the middle but it would triangulate the mold and it keep it from moving when you pull the vacuum.
Hope that is good advice and isn't redundant.
