Undertray/bellypan
 

So I'm thinking about building a under belly pan. (I think that's what you call it)

Is it possible using RV under belly material but for a car?

I copy and paste the specifications of it:

Mobile Home Belly Bottom board Closure 4 ft x 14 ft
Mobile Flex is a special bottom closure, woven from black high density polyethylene and extrusion coated with a continuous layer of low density polyethylene.
Mobile flex is totally impervious to water. Its strength can not be adversely affected by moisture.
Mobile Flex is produced from a material that has been tested for durability and weatherability.

You can buy it on amazon for 15 dollars but you need to buy the special tape to attach it on the RV i think.

So I figure if it works for RV/motor homes/custom limousines I can use it for a car.

What do you all think? My car is new so its mostly flat but there are a few spaces where I think smoothing it out will help with MPG.


Thanks

From what I'm seeing in the Amazon pictures and description, this is designed to be tacked to a solid surface, like plywood. Otherwise, it's similar to a tarp. If you were thinking of just stringing this across the gaps without any flat support above it to attach it to, I wouldn't do it. I think it would work it's way loose at highway speeds and behave like a tarp...loose and flapping away. Just my 2 cents.

Yeah I think your right. Thanks for the reply.

Polymetal. More expensive than plywood but lighter and impervious to water, if not fire.

Plus, it's prefinished.
