What materials to use? -- Looks neat!
 

These images look neat but...
What type of materials should be used for this project? And how much would it cost? I'm new at this. :confused:

Best thing to do is read the forums and git some ideas on what may work fer yer needs. Some may suggest coroplast to metal sheeting.

Not to burst the bubble, but thats a photoshop.

The question is do you want it to work and be cheap, or do you want it to look professional/stealth?

One cost much more than the other.

Yes, the website/blog says it's Photoshop. So what?
The pics would indicate that it should look clean and professional.

The key to making anything look good, is skill with tools.

What most do is get an idea plan it out then make a template from cardboard tape it on test it, then adjust. After that is done they go to final production using coroplast, metal, or fiberglass.

How it looks depends on what skills you have and how much time you spend on it.
