Hi guys, first post here. I have been recently looking to make some carbon fiber parts from molds. I have searched around quite a bit and watched a ton of videos and really liked the unimould kit from EasyComposites. The problem is I am in the U.S. and can't justify spending nearly $200USD on shipping alone. I really like the system as it seems to be the most in depth kit I have seen. Is there an option for those of us stateside? Through all of my reading, there seems to be so much conflicting info out there about what material works with what and what doesn't, it would be nice to have a set stack of materials that for sure works so I can spend time working on my skills rather than trying to deal with incompatibilities on top of being somewhat new to composites. Thanks!

Nah iso resin is just a higher quality resin than ortho resin, but the main difference is just better water resistance. It does have slightly lower shrink, but at the end of the day it is still a polyester resin - it's just one that you could use to line a water tank for potable water.

It's also not the difference between saturated and unsaturated, that just refers to the chemical structure of the polymer. Filled tooling resins have a thermoplastic filler that expands at the same rate that the resin shrinks, effectively canceling out the shrinkage and giving you close to zero shrink.

As for the Duratec, the 904-046 is the normal one. For what you're using it for, you could really use any of them, but the vinyl ester costs more. The vinyl ester is just for water resistance for use on boats, so not much benefit for the extra money.
