Infusion and envelope bagging

Hi guys, I've got a project at the moment were the mould has been supplied by the customer and wants a carbon part making.

The problem is the customer is used to wet lay fibreglass and I don't think he fully appreciated the ins and outs of vac infusion so has drilled a few holes and cutout in the mould.

Now I've had one go already having sealed the holes the best I can but it's just not worked properly. I know someone on here once said that they infused parts by envelope bagging the whole mould and infusing. Now this would solve all my problems but can't help but worry the resin is going to go around the back of the mould when it reaches the edge of the stack?

Has anyone got any experience envelope bagging and infusing and did you have to do anything special?

Thanks in advance

Thanks for the confirmation, managed to get it to work in the end, turns out his MEKP wasn't happy with my resin causing the gel coat to wrinkle

The issue I'd have with running spiral around the outside is the resin hits places up to 30 min before its finished so would only want to try it with mti hose but haven't got the budget for that just yet
