I re-did the inner side skirts by replacing it with 6mm thick coroplast, it's much more sturdier and less "wobbly" than 4mm coroplast. I also had the plastic store cut it for me so that the skirts came out straight and even (instead of crooked and janky) lol.
I also got around to installing the outer side skirts as well. Prepping for paint with black Plastidip. I decided to paint the oem side skirt as well for the purpose of blending in with the coroplast side skirt. Hopefully it will make the coroplast side skirt less noticeable.
My fiance hasn't noticed it yet
It's been really windy this weekend, so I couldn't test out the combined effectiveness of inner and out skirts. However, i do notice that wind noise has decreased a bit more.
