I've decided to grill block about 90% of my grill on my lumina and see how it does. Below are pictures of everything I will be blocking (in yellow). I will be using cardboard to get the specifications right and then use it as a template for coroplast. My main concern is how to attach the coroplast properly for easy removal. I was thinking of using a velcro system to attach the coroplast on the small left and right vents that have little use and are slanted about 70 degrees from the horizontal. For the main grill, I may just use zip ties.
Any suggestions about anything?
