Hi Jim13,
Cannot see why stainless steel wont work. Polished 316 marine grade stainless steel will look amazing.
I have been busy designing and prototyping some new laser cut profile side panels out of 5mm Mild steel. I have been looking for a 20" solid deck Scott Bonnar for almost one year now with no luck. As I could not find one I decided to make my own. Plan on building two 20". One solid deck and only twin rail deck. Best of both worlds. All powered by Subaru robin motors.
