Yes, you are right, Uni-Mould is cheaper, apologies.  I made a mistake with my numbers.  Still, a female for my telescope tube project is running to £600 (plug and female).  And that is before I even consider composites, vacuum bagging and infusion.  Any advice to bring the cost down?

Epoxy is also harder to work with. Systems like the Unimould are extremely forgiving and easy to use, epoxy systems are significantly less forgiving and often hard to repair if you do make a mistake.

You must have got something wrong here. I guess you are talking about the moulding paste. You will need at least the high temp gelcoat in addition. This will be least 110£ for the smallest batch, wich is 5+1kg. For less than 80£ you can get the small unimould starter kit, wich is 1+1+5kg + csm. and the paste has to be used much thicker than a csm mould. You'll get much more mould for the same money with the unimould system. And the high temp paste is only more versatile if you use high temps. Basically only when using prepregs.

EL160 renders Uni-mold redundant? Can't see the point in paying more for a less versatile system. Unless there is a benefit of Uni-Mold I am missing.

They are completely different resin chemistry.  The Uni-mould system is based on vinylester and polyester and is suitable up to 90C.   The EL160/EG160 high temperature epoxy system is epoxy based using a high temperature epoxy that is suitable for use up to 160C which is much higher.

Just wondered if anyone could explain the difference between the above?  The high temp system seems simpler and cheaper.
