Anyone tried using Ultracote or Monocote on their car? I build RC airplanes and use this to cover the wings, fuselage, etc. Its an iron on plastic. Its extremely light, durable, fuel proof, etc.
Looking at my corolla, it looks like the grill can come off in a manner of minutes. I'm considering buying a roll of ultracote, stretching and sealing it over my grill, and reinstalling. Should be simple, cheap, and easily removable if needed. Rc planes going well over 100mph have no issues.
Aside from the grill, this could easily seal gaps or other areas of the car, added aero framework, etc. It is available in many colors, including clear. Might be good for sealing open headlights.
This article has tensile strengths, puncture resistance, etc, pretty much everything you need to know about the technical details of the material.
