powder coating is the only way...but, as Shawn said... it wont last. any sediment at all, it comes off after awhile.
stainless steel for me too.
I have the stock prop that came with mine...it's black. I just "97 cent walmart rattlecan" it black really quick it if Ill be towing the boat to a crowded place... just for aesthetics.
Doesn't last one trip.
ill stick with the SS.
