First of all, thanks for taking the time to look in here.

I am getting ready to do some Norrell coating and I want to start out with my Ruger MarkII that has been a favorite since college. I am wondering if a smooth blued firearm needs/should be bead blasted prior to applying the coating?

Also, I have had the Mark II threaded for use with a supressor and would like to know if applying the coatings to the threads will inhibit the use of the can. How well will the finish wear after threading and unthreading the supressor and thread protectors?

Thanks again,

In my experience, Duracoat will NOT adhere well to polished steel, the steel really need to be porious so it has something to grabb on to--it will look good to start, but thats it. I duracoated a S&W auto once, top of the slide and bottomside/front of the gripstrap were all lightly sandblasted(matte) while all other surfaces where polished. The porious matte areas held up forever--never showing wear until I sold it, while the polished area chipped easily with normal use.
I would tape off the threads, because repeated on/off could potentially start chipping/peeling into the non-threaded area.

Would sandpaper do the trick if it was sanded fairly evenly?

I suppose technically speaking it would--you would be breaking up the polished surface, creating a porious condition like sandblasting. But why not call around to a few machine shops and see if anyone would be willing to do a quick blast in their cabinet of a few small parts---then break it down and have them do it--a couple of minutes is all it would take, probably while you waite.
Any of these "finishes" apply with VERY THIN coats, so to adequitely cover up what you are asking (and look good) may take several coats--which isn't necessarily a good thing.
my 2 cents

Thanks guys for the input. Now I need to figure out what I'm goinig to to do for the rear sight and the detail work on it. I'd like to give it a coat, but am concerned about coating it stuck.
