I am looking at making the switch to poly on some of my future builds and was wondering if poly will "sun tan" the way nitro does. Can you tell me if poly will turn amber with UV exposure? Thanks!

I think polyurethane will "yellow" some, but not give the aged amber look like nitro. Polycrylic will not yellow at all.

Thanks, I just didn't want to waste a bunch of time waiting for something to happen that was never going to.

Why not mix a little amber tint in your poly? Or use an amber shellac as a sealer before poly? This is amber shellac sealer over tinted timbermate.

Amber tint is also a possibility but there is a certain tint you get with the UV that's hard to match and if you can just throw a jar in the window it will be ready when you are ready to finish it and you don't have to do all of the experimenting.
