Heat shrink wrap

Has any one tried using heat shrink wrap for aero mods?

It has been suggested and I think someone even tried it when making an aerocap for his truck. Its not a widely used technique though.

I was wondering if it lasted, say for somthing like a see through aero truck bed cap or if it should only be used testing.

Mine lasted for 4 months with only minor deterioration. I found that on warm days though, it expanded back out and became loose fitting. I used the black poly for crawl space covering that you can get at a lumber yard. I used a heal gun to shrink it, and it required a lot of time to do so compared to using a large propane torch. Both myself a Fubeca used the same method, built a plywood aerocap the covered with heat shrink poly. The real heat shrink was quite a bit more expensive but maybe won't get loose in the heat.

If I do it again, I'm going to make my cap smooth with plywood again, but then use body filler to fill in the imperfections and paint it with an exterior grade primer and paint, I figure if the paint can stay on a house for 5-10 years, it should last a awhile on the truck.

Something similar- if you have rather shallow draw you could probably figure out a way to vacuum form a piece of plastic using a large oven and a shop vac, providing the buck is designed properly (with plenty of holes). Split the aero cap into a few pieces to make and bolt them together later. Maybe do fiberglass for the majority of it and vacuum form a window with complex curvature.

Perhaps a powder coating shop or sculpture foundry would allow you to use their oven/kiln?

I wanted to use some to seal the tail to the car but I could not find a good source that was cheep.
