For all the armor and helmet? Figure 5 dollars a can of paint...depends on brand and location. I use about 2 cans of Huntclub, 1 can of the bauhaus yellow, 2 cans of silver, 2 cans of primer, dullcoat maybe 2 cans, flat black 2 cans, claretwhine one can, royal blue i think one can, flat white one can, thats just armor and jetpack add another can of everthing besides yellow and add moss green, for ROTJ, sandpapers towels masking fluid or toothepaste and then ull want some other things like brushes and what not for the masking fluid, space to paint and all. I may have left out some things at least 11-15 cans of paint, if your doing a helmet also then add depending on helmet style add 5 or so more cans so 20 cans at 5 a peice thats about 100 bucks or so plus sandpapers and other stuff masking fluid about 15 bucks for good stuff....so maybe 150 in all for all the stuff ull want to have
