Exactly, I was in a plant 2-4 years ago that made front cradles and other parts, they had the epoxy mil thickness set to .3 and did a salt spray test at 13% solution (33% is what I was taught??) every 200 or so parts, hoping to get in 250 hour range.
Pretty crappy and put that in the sun, won't last long.
They we looking for cheaper yet and asking about SS direct to metal.
