Ok so this is a stupid question... I'm making a section of mould that is upside down (underside part of a car sill so I can't turn it around).

Im really struggling, its mostly falling and I only have around 1ft of clearance so Im lying on my back doing it Sad

any tips?

Knock up in mdf a former/insert you can press on the inside of the mould from underneath to force/hold the fibreglass in place while it cures. Cover it in release film or similar so it doesn't stick.  You could even do most the lay up loosely on top, then lift it into place, take out former, work fibreglass where needed, then when happy put former back in place and jack/support it in position while the resin goes off.
