How to weather proof decorative steer (cattle) horns?

I bought a pair of steer horns to put on the outside of my jeep. I don%26#039;t have access to a garage and during the day my jeep is directly in the sun. I live in So. Cali so the temperatures goes from 120 degrees in summer to 20 in winter. What can I do to the horns to help keep them weather resistant? Something that will keep them from getting damaged by rain and a whole lot of sun. I was thinking perhaps dipping or coating them in RainEx to help keep them water resistant, but I have no idea for the sun. Maybe I should just Armor All them every once in a while? Will the sun even be a problem? They%26#039;ve been polished and are all pretty and shiny, I was just afraid that they may splinter or crack from drying out in the sun or heat. Any advice thank you.

polyurethane, in a sateen finish would be nice, several coats, let dry good inbetween coats.
Reply:you could polyurethane them so they don%26#039;t dry out however the sun is going to be an issue for the color only. the color will fade after time of being in the sun. the best way to protect them would be trying to find something to slip over them or tie on while you are at work so they don%26#039;t fade. good luck and happy holidays=)
Reply:I am a cane maker %26amp; have worked with horn %26amp; a traditional finish should be of the oil or wax variety, but you can use a marine spar varnish.
