Started mine today - will need a LOT more than 4 boxes (but I think my f/glass stuff is in smaller packs - got it from CPC.co.uk). 4 boxes hasn't even covered the first layer.
But in all fairness, I'm going mad getting the coverage right.
The key to this entire process is to TAKE YOUR TIME.
Having a lot of fun doing it too
Will complete the first layer tomorrow hopefully.
