To be perfectly honest, I think you have an issue with either your resin (too high viscosity) or starving your part of resin .. I've just infused a tank cover (around 0,7 sq mtr, since the mould used up a complete standard Unimould kit ..
) It does not have a single visible pinhole in the whole of the "usable" area... This was with a microscopic leak that I just could not find, dropped vacuum completely in 5 hours --- but I just kept the pump running .. Yeah ... I know ... should have spent some more hours finding the leak ... or rebagged, but it was a first test of the mould and some new lay-up ideas (for me at least
) The part came out near perfect, apart from the pattern of the carbon having shifted slightly making my intended stripe of spread tow off center .. I need a better way of making it stay in place when fumbling around with the backing layers and bagging ...
