Okay so what can you tell me about the order of the things I need after I stipple the layers of cloth with Resin?By the way I appreciate your time and knowledge... I'm just a home car project bunny, you need the likes of Oekmont and Hanaldo to give you expert guidance. However, here is how I do it :-) First off, I would never mix fibreglass and carbon an anything that is subject to stresses due to their very different stretch/deformation properties. This is how i used to do it. Once you have laid up your material (making sure that the carbon is fully saturated) cover with a peel ply, then a perforated release film (making sure that there is plenty of spare material in the corners) then a couple of layers of breather cloth. Place in the vacuum bag and slowly remove the air whilst pushing the bag into all the corners. Once you are happy that there are no bridging issues, leave to cure. I went for the best vacuum my pump could provide, but others on here would recommend only going to 50% vacuum and they are more experienced than me (but I still disagree with them :-) ).

I used the same Resin for my mould and that was mostly chopped strand which seem to work okay. CSM fibreglass is usually held together with an emulsion binder, which isn't broken down by epoxy resin. You will probably get away with using the very light emulsion bound CSM (100gsm) but you will have difficulty laminating with heavier mats. With epoxy you should use a CSM using a powder binder. If you use the woven cloth fibreglass this has no binders so works with all resins.

I'm planning to coat my Pre Waxed polished mould with Resin, lay some Carbon Fibre, stipple it with a brush, might lay some Glass Fibre on top of it, stipple it some more with resin and then I'll be ready for the next steps. Is this the right things to do next, lay Peel Ply, then Perforated Release Film, then, Bleeder Ply and finally the bagging itself with a pressure of -5 to -8 HG until it cures, does this all sound right? First off, which resin are you planning to use? I ask because epoxy resin doesn't work with standard chopped strand fibreglass.
