I'm currently making a buck to make a mould for a diffuser. Based around a wooden construction with a fibre board to get a good curve. I am wondering what a good sealer for this would be.
The base board is MDF... having already taken a mould for another part using MDF as a base I know that this will not absorb the resin. However I do need to get a reasonable finish to this area on this occation/
I have seen on other forums that some people use Bonda G4 water seal... which isn't easy sourced. Are there other alternative such as a concrete seal? What have others used...
I also need to finish off the edges of the diffuser with a fillet or newplast before moulding commences so it will need to either go over or under this.
