Hi boys!

My oven doesn't work jet and I put my new mould outside of the workshop. 4 pieces split-mould dissasembled and been put separately in the sunlight. Gelcoat side face to the sky. Surface reached 50-55 degree Celsius for a couple hours. When I was putting the parts together just noticed that the front panel is not fitting perfectly. Cause of the distorsion of the side panels. Can I solve this somehow? Let's say with controlled post cureing (with assembled mould)?
With some force I can push back the sides in position so still can use the mould. Just annoying...
Vinyl gelcoat, 2x100gm2 CSM coupling coat, 4x450gm2 CSM with tooling resin.
Pictures attached. Distorsion is about 10-12mm.
Any idea why this happend?
