What to use for undercoating?

I've fully media blasted and epoxy primed my Duster and I'm getting close to finishing the metal work, subframe connectors, relocation boxes and minitubs and I want to undercoat the car with something. I've been looking at Eastwood and I'm liking the Eastwood Black Undercoating. Looks tough and can be washed down if it ever gets dirty...

Anyone have any suggestions?

Anything to steer clear of?

Thanks
