the tank is made of metal and i thought someone might want to paint
camouflage colors on something so this may help as a reference.
I repainted my enduro bike (1972 Yamaha CT2). I used a "sand" colored base
coat, then random shots of "hunter green". I then sponged in a little flat
black. I used a handfull of maple leaves and sprayed around the edges here
and there with the green and sand paint. Total cost was about $10.00 for
the materials (spray can paint, sponge, sandpaper, and a handfull of
leaves). The only problem is that gasolene will lift the paint. Within the
next couple months the paint gets a little tougher and it's not so much of a
problem (just fill the tank carefully). A two part clear would do the trick,
so maybe i'll have a friend clear the tank when he's painting a car at his
shop next time.
Here are a few pics.
