How to paint strip a large mode/tank?

[eldargal]

I just found my first ever large model, a falcon grav tank from when they were first released by GW ages ago. Anyway, the paint job is rather poor by my current standards and I'm thinking I will redo it, but I'm not sure how to strip a model which sits 75% out of the simply green tank. I'm not particularly keen on filling a bucket with the stuff as i think it would be wasteful.

How do you strip a tank?

P.S. I would ask my brothers but they are all sleep, insomnia gets annoying after a few days.
