Ouch! That looks like it was at the bottom of a lake. and it won't buff out! Art has done some parkerizing and can guide you through the process. Pretty simple if you can boil water, yer good to go. You have access to the tools and materials needed for the prep. You will have to completely disassemble the gun so I hope you have done your homework on that and how to reassemble it. Other than that, if you don't want to DIY it, talk to Henry @ supertech as he has a guy that can do the job or just send it back to Colt that way it will be a factory re finish. Last I knew they charged $200.00, comparable to most other shops. I do not parkerize as I haven't had to learn the process. Art is your guy to talk to about it. His gun came out perfect.
