I did, I filled in the one directly above the overhead console. Mine was rusted out and leaking. I ground out as much rusted metal as I could, used a mesh that's used in construction, then filled in with bondo. I repainted with the spray can estate green color, and it doesn't leak. Filling in all of them would require painting the whole roof. A little pricey, but if you have your own paint sprayers, about $250.00 in paint. Base coat, clear coat, primer, sand paper. If you keep your roof waxed at least twice a year, the possibility of rust is greatly diminished.
