What are some of you using for belly pan paneling? I am still going to need at least $100 in these panels not to mention fasteners. Any thoughts on this. I think my best bang for the buck is under body paneling to smooth the air flow under the vehicle.

Sounds like yer describing FRP (fiber reinforced plastic). It doesn't hold up to hard impacts very well and will fracture/snap quite easily. It's much heavier than Coroplast and can be cut with a cutting wheel/fine toothed jig saw. It will sag without support beams when used in a horizontal configuration. I built a frame from metal 2x4 studs (so I wouldn't have to drill into my frame and it would be easy to remove fer maintenance) and reinforced it with wood inserts in key spots. I used 4mm Coroplast as my final cover but I did try luan panels as my first trial material as it was inexpensive and easy to work with. I installed crossbeams as attachment points fer my belly pans.
