yep, can't add up as well as can't spell !!!!!!
I only state that number of rattle cans due to what I used when I painted tank panels and tank, took 3.5 cans, had half a can left. That was three coats on them. Full colour change would require at least one more for rear panels, so perhaps get away with 5 cans in total. Its a shame they are not cheaper. I thinbk if I was to change a colour of a bike, I would go for a straight colour, like red or white, you can get six cans off e bay for about £30.
