I just sold my set of ie-1 irons. Great irons! 431 steel is so soft! I could go over mine with a scotch brite and they would look like brand new.
Now for the blue… I hated it as well and stripped it off. Sprayed it on the blue, let it sit for a while and used a tooth pick to scrape it off. Only thing I left was the black PING. Looked 1000 times better.
