What to use for undercoating?

I used Herculiner and sprayed it on inside and out of my floor panels. I also used it on the inner panels as a protectant. It worked great. Just buy a cheap undercoating sprayer. You can thin it a little with lacquer if you want a smoother finish. Look at my pics of the car upside down and sprayed.
Good luck

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
