Hey- nice to see you were able to try the trip strip idea. Nearly invisible isn't it ?
That stuff that I spoke about in my last post for use as a flexible spoiler is called wall base.
It is sold at places like Lowes - here is the link
Shop Flooring : Wall Base at Lowes.com
It's $ 25 bucks for 50 feet of the stuff, but is also sold in 4 foot sections for less than $ 3 (
$ 2.36 )
It is made from the same type of rubber that you see on cars, but is more flexible. It has a very professional look to it, unlike garden edging which has a cheap shiny look.
It also holds up quite well to curbs, and is very easy to cut.
Here it is on my car after almost a year and hitting several speed-bumps.

Hate to say it but the spray paint on the 'noodles' will most likely flake off in a few months time. That type of material doesn't take too well to paint - in fact some types of rubber will shrivel and melt when you paint them, or will not let the paint adhere at all.
So are you going to tuft the car ?
Even tufting the windows ( around the sides too ) will give you an idea of what is going on around the car. You don't even need another person - just look in your rear view mirror and observe what the tufts are doing on the windows.
Right now you aren't really improving the aero
all that much - in fact you may be making it worse with the air-dam because you have increased the frontal area of the car. Have you considered a belly-pan instead ?
The big draggy areas are your wheels and the rear of the car. Trip strips and such may help, but but only a tiny amount. If i had a car like yours, I would add a professional looking kammback, a belly pan, some 'moon' wheels, and a ( stealth ) grille block.
I like Minis. They have a neat style that reminds me of the original Minis. I'd keep it as original looking as I could.
