good luck with it its a big job mate. i dont want to scare you but sometimes i think to myself is it worth it as i have started one for myself over a year a ago. its only a 6X4 box but the work i put in it is huge bigger than the canopy. by the time you cut the rust out repair the bits with rust treat it prime it than paint it and then put it all back to gether man it long procses.
