Sorry to hear and see that. But this would have happened with any other bagging technique. It looks like your mould wasn't tempered high enough, or your mould resin just isn't suitable for the...

Yes, I know the air would be atmospheric, I was working on relative pressures. otherwise the 14 would be 0. With a vacuum within the ribs (I would be surprised if they were airtight, the combination....

How is the trimming and repair work coming on? Do you have a more or less final weight yet?

Hopefully :-) Any issues with using your repair resin, as this will speed up the repair process? Steve

Just spoken to Rich who confirmed that there are no problems with using this resin.

Just remember to mix small batches as the pot life in this weather is likely to be sub 10 minutes, so small batches at a time and you will have around a 2 hour cure time on the resin.
