I agree with brushing, this stuff goes on really thin but it dries vary thick and vary solid. I asked the sale person how much I would need for my truck frame and he said a quart should do the whole thing with two coats. One thing to know,,, When you open the can it is real hard to re seal it after use. I waisted a bit of whatI had because of that so I think it is best to have everything prepped and ready to paint it all at once if possible.
Good luck
