Best Matte Clear Coat for Running Tanks Outside

[Studiocat13]

Hey Guys,
I'm about to wrap up painting and weathering my new Heng Long Panther G Tank and would like to see what people are using to lock in their work and protect the tank from water when taking the tank outside for a little more realistic weathering, mud and fun !

Thanks in advance,

Brad

I use Alclad lacquers and been really happy with them so far even in the Texas sun.
