Hi, I have used West Sixt too when we produced a jet for a short run project and found it to be very good, one interesting feature about the Six-10 epoxy is the way is thins as you mix it and then reverts to a gel like consistency after, one issue however is when you are making a fillet by running a finger (naturally with a latex glove on) it tends to revert to is thinner state during this action which means it does not fillet/smooth as easily as Hysol 9462.
As mentioned Hysol 9462 is very good, thixotropic (non sagging) and easy to apply and fillet, yes expensive but well worth it in my opinion. There are other Hysol products too which are cheaper and also very good like Hysol 9464, this is a slate grey product so maybe not as pleasing to the eye but cures slightly quicker than 9462 and sets rock hard too.
Grab a gun but no need to use the nozzles, just squeeze some into a small cup and mix by hand - apply using a syringe which are as cheap as chips.
