    If you are using west system 105, it will cost about £100 for 5kg epoxy and £50 for 1kg hardener. Depending on how hardcore you want to be with the aggergates you will end up with a mix that contains anywhere from 7% (hardcore) to 20% (lazy git) epoxy/hardener. You will also want couple of calibrated pumps for £15 - £20.

    Assuming you want to fill 1m of 80x40x3 steel box internal the volume is 0.002849 metres cubed (or about 2.8 litres of space). 6kgs of epoxy/hardener is about 4.5 litres so a 10% mix would get you 16m or a 20% mix would let you fill 8m. The total cost include the aggergates (if you can buy them in small enough quantities) would be about £200.
