Hard to tell right now if it helped FE. 30F and wind and rain all morning, plus I had to drop 2 kids in 2 different places on the way. The way home should give a better indication if it is helping.
Have not seen much sun this year so I'll have to wait and see if the curtain heats up and stretches. It was about 40F when I installed it, had to lay boards on it to keep it from blowing away. (Where's that global warming anyway, it's June and I am still running the woodstove.) I stretched it pretty good on there and used a screw and washer at least every 3" with the rough side of the washer down.
A coworker happened to be following me part of the way this morning and he said it looked like a Corvette or Delorean, till I turned the corner then he knew who it was. I was actually shooting for the tail end to look like my old trailer in the pic, which I made to look like a semitrailer, but then I realized I didn't have another license/backup bezel. Now I see it does look kinda cool, like a vette.
One thing I noticed this morning is the curtain was all fogged up so I had to use my mirrors. Another thing is I am getting reflections from the inside of the framework and back of the car which makes it harder to see. GM solved this issue with the windshield of the APV vans with black carpet on the dash, so I may look for some black carpet and fill the area.
This is something I have been thinking of trying rather than the shower curtain, and is cheaper than plexi or lexan. But for now, I want to keep it as cheap as possible since I don't have much money to spare.
