then you gotta polish the mould up and the process is repeated on the inside ofthe mould to make another bumper
you left out the bit about making the flanges
this bumper has return flanges in the wheel arch, so i have to make flanges out of card and then lay these 2 end sections up first. when they have gone off the card is removed and the main center section can be laid up. once its all cured the 3 sections are drilled to take bolts. then crack the mould off, bolt the 3 sections together and lay it up.
will probably use some grp tissue after the gell coat as there are some tight spaces and i dont want any air gaps.
i have a whole report that i have written on how to mould stuff, but cant post it up cause the example i used was from work and the component used aint in production yet so can let you see it
if your interested luke then il post up the stages of this bumper as i do it
