You can buy two sets of West System pumps and use the biggest one from each, but a full pump of structural Aeropoxy is overkill. Put it in squeeze bottles and it will be just like hobby epoxy. I've never used colloidal silica before, but when it comes to fillers it only takes a little to retard the sagging.
If you are worried about the mix ratio, don't be. Just judge by the color: if it is too milky-whiteor too clear of an amber color then just add whatever is lacking.
