I'm making some fairly large panels for a motorcycle project for the full fairing, seat etc and so far have had pleasing results. I'm using three layers of 1x200 and 2x 450 carbon twill and resin infusion.
The moulds are multi part moulds made using the unimould system. Before laying up the carbon and bagging it I have applied four coats of easylease with 15-20 minutes between each and then a final fifth layer that is left for at least an hour before infusion.
I've watched Matt on all of the easycomposites videos demoulding parts and it looks effortless. Firstly when I'm removing the peel ply, it's really hard to do. Matt tears his in strips and it comes right off whereas I have to use all my strength to get it of free the carbon part and I'm no weakling! Then, where Matt's parts virtually pop out of the mould, mine need dozens of polypropylene wedges knocking into cracks to get it to come out. This Is largely, bar a few details, a flat panel and it takes me about 2 hours to free it.
On two of the five things I've made, part of the mould has come off with the part meaning major repairs if I wants to use the mould again.
I believe I've followed the instructions for easy lease to the letter but demoulding is a nightmare. What am I doing wrong or does Matt in the video just have superhuman finger strength?! Any suggestions appreciated as I'm about to move on to the complicated nose cone and want to get that out more easily. Thanks.

Hi!
U need to use sealer before adding the release agent. I recommend Chemtrend Chemlease® 15 sealer EZ. Google it and u will find instructions. If your mould is even a little bit porous, this stuff will help u a lot. We always use this sealer before adding any releasing agents. U need to do it just at the first time when u take mould in use. no need to add it later on, unless u sand the moulds.
