Well.laid sections will often look much better than a single piece with weave distortion, even if the join is visible so this might be a better approach.
I can only comment on using Cytec's Aerofix 3 with EC's resins, but I've found that it leaves next to no trace if used sparingly
I've also left moulds overnight with just the fabric apllied, including on vertical sides and nothing has come away so this shouldn't be an issue either. It will lose some of the initial tack but not enough for it to just fall away.
