I actually painted on the balcony with that blue plastic cover that you see. I didn't make a mess so she didn't mind. So what do you guys recommend me do to hold the coroplast on the grill fins? I was thinking about using zip ties first, because I have a lot of coroplast and I can always remake if something goes wrong.
I took the van for a test drive and I liked my results. I drove 50mph and averaged 32.1mpg. I didn't take more pics of when I reached 32, because I didn't want to wreck. I didn't use the AC and I had the windows up. I know this isn't that much especially for the highway, but I haven't been able to achieve over 26mpg at 50mph, so I feel pretty good.
