I don’t know much about props , Tom does.
But if you’re not bending blades or gouging them up frequently, aluminum is ok.. paint has no purpose other than looks. IMO
At $80 Id get two. $200 for a cheap stainless. I run Solas aluminum on my 115..... 8 years on this one. Spare in console..
I like the look of worn paint tips..... JMO
