do it!
i have no plans on putting a good paint job on suzi- she only gets paint in little bits and pieces to mabe keep rust away. whatever is laying around mostly. spray cans, brush on, dip or other.
i did use a brush/roller on an old work truck, and the thing was no longer embarassing to run thru town.
used "implement paint"(1 qt white, 1qt black)-black for the wheels and bumpers, then mixed the white in and painted the body. quick cover but long dry(esp. how thick i put it on).
your color is interesting, but the paint still looks good.
