So hears another question for the pros. Is there any reason why the leading edge of the wing has to be painted? Just curious as I debate a Horton removal sportsman install. My Horton is red to match the stripes on my fuselage and I like that it helps melt the frost off faster. That said, my polished 150 melted off fast then any of the other planes at the flight school, so I can see a stainless leading edge being beneficial from that aspect. So why not just clear coat the leading edge? I do like the look, kinda matches the polished spinner. Will it hurt anything?
Thanks.

Clear seems like a good finish. Not, sure about having to prime? Does it work on bare aluminum?

Turtle Wax is my clear coat.

I rocked the unpainted leading edge on my Sportsman Stol for a couple years. No reason to paint it other than to make it match your paint job. Polish the aluminum with some Nuvite if you want a mirror finish. I'm not sure I'd try to coat it with anything.

I think a polished cuff would look pretty cool on a painted wing.

On my 182 SPORTSMAN leading is polished Alum. -never bothered to paint . Polish with Truckers wheel cleaner -about a buck at Walmart.
