Lots of information and familiarity in the forum on Coroplast (brand name for corrugated polypropylene often called "sign board") and ABS plastic. However I've stumbled across something which may expand our bag of tricks a little.

That is an awful lot of support behind that plastic sheet material. Maybe more work than it's worth?
Another product line from Quadrant which caught my attention is below.
Lightweight construction components (LWRT)
SymaLITE, 3D molding, low pressure pressing, construction, undershields, corrosion resistant, wear resistant, covers, noise absorption, protection, thermoforming, one-step molding, high resistance, part integration, handling - Quadrant

SymaLITE, a high-strength composite, has become established as an all-round material for extra-high weight savings combined with outstanding mechanical and physical characteristics. This product group of glass-reinforced thermoplastic mixed-fiber fleeces can be processed inexpensively into three-dimensional moldings by low-pressure pressing. ..............
The SymaLITE applications also extend to undershields. SymaLITE permits the production of an almost continuous corrosion- and wear-resistant undershield which, thanks to the material’s properties, is extremely light, inherently rigid and also acoustically effective.

I wonder if used in a flat sheet if it could be used as a belly pan on an existing automobile, or if it needs all of those flutes and 3d moldings?
Maybe with all the heat under a car, metals might still be best. Not sure, as I've never done a belly pan.
The HDPE plastic (High-density polyethylene) chin spoiler I put on my truck, only lasted 3-years (now held together with foil tape). Mostly because people kept backing up into it, but also major UV fatigue and brittleness is evident.

Ideas and experiences with other plastics are welcomed. I'm just trying to share some information, and maybe learn more about it.
