This isn't a repair per se,but if you take the black wrinkle paint used for valve covers,and spray the woodgrain insert with it,it comes out looking MINT.You won't have the "wiper/washer" and "lighter" lettering,but you don't have to fill the holes in.Filling in the holes,if done right is the way to go,but I thought I'd offer an "alternate" option.
