Just bought a Goff G2 door. It works great and keeps the bay much warmer than our old folding plastic strip wind curtain. The problem is that despite the clear panels, it looks very dark from the road and we look closed. I'd like to put some white reflective letters that spell "OPEN" across the clear panels. Is this a good idea? Has anyone done this or solved it another way? DYI or get a pro? Any help would be appreciated.
