I did a lot of seam and rust work on my van using heavy duty metal primer
and spray cans of VW paint.  The objective was'nt to have a work of art
but to protect my van from further deterioration from rust.  The results
stopped the rust and improved the loook of the van but its far from a work
of art.  Best of all the whole job cost only about $60 in materials but
countless hours of sanding and other prep work.  If you want a your van to
look like a work of art you will have to spend a lot of money but for
those who would rather put their money under the hood or into another
camping trip there is no need to spend a lot of money on this.
