Hi folks,

I'm trying to do my first infusion at the moment, and I'm being driven crazy by the vacuum leaking.

The mould I made myself, it's been painted with 2k automotive paint & clearcoat, the surface finish is good but not perfect (a few minor bits of 'orange peel' texture).

I've tried bagging it three times now, the last time I tried applying the tacky tape to the bag first (which I found a lot easier actually), each time it will leak though.

I have spent ages working the tacky tape in to make sure it's firmly pressed down, no creases etc. Where the vac line enters I made sure the connector was clean and no creases etc.

Initially I had applied release agent to the whole mould, including where the tacky tape goes, after the 2nd attempt I tried to clean this off using brake cleaner in case it was causing an issue, but still no vacuum. I don't know if that could be the issue, but I presume the brake cleaner would remove the easy-lease...

I can hear the bag moving slightly as the vacuum fades and it seems to come evenly from various places, so I can't pinpoint one place where the leak is occuring.

Would appreciate any tips on this as I'm going mad!

Thanks,
Rich
