Sometimes I have to order some colour as pigment as it's not available mixed, I then have to add it to clear gelcoat to make it up.
If you need to fill first before the top coat you use gel, it is only the final top coat that is flowcoat.
It's all to do with a chemical and mechanical bond....
Wax makes gel into flow coat, the wax comes to the surface stopping any air, this makes the flowcoat dry with a hard finish, where gelcoat dries sticky ready for the next layer.
If you were making a console using a mould then you would just use Gelcoat as there is no air between the mould and the gel so therefore it dries hard against the mould and sticky on the side you can see.
Thats got to be worth another tenner from someone
