i think hes saying the opposite

No MG, i think he's refering to the actual ratio of resin to cloth when manufacturing, if there is too much resin it will become thick (will take forever to dry) and will be more brittle because of it.
The same is when you dont use enough resin, it becomes weak from not being bonded enough....

Or so ive been told

Is this what you meant Blue Deluxe.

The purpose of the resin apart from providing finish etc is to hold the reinforcing (glass/carbon/kevlar) in the correct position to provide stiffness and strength. It also protects the reinforcing and provides compressive strength.

Too little resin and the fibres aren't supported and are not able to develop strength. Too much and you have a heavy part that probably wont perform as well. Also the reinforcing may be allowed to move out of its ideal location. In the thicknesses we talk about for panels it is more about weight than anything else if there is too much resin as the resin setting is a chemical reaction. It has to be thick to be a problem with the temperature of the set affecting how straight it cures etc, building in strength issues due to deformation.

If you are getting any sort of epoxy not setting correctly, it is potentially because of a number of things including poor mixing (most common), old chemicals, bad weather etc.

I'm no expert and someone will probably pick a couple of errors but there you go.
