Thankyou Exactly.  T304 is not that cheap and quality welding stainless?  I know I don't stand a chance.    also I personally wouldn't put anything less than t304 if you plan on keeping your car more than a couple years.  Mild steel will be rusted by then and high temp paint will not stay on either.  A coating process may stand a chance.
