Hey all! New to the forum and looking for some guidance. A friend of mine found a MGC Thompson in a basement and gave it to me as a gift. Super excited! I’d like to clean it up to the best I possibly can and maybe hang it up in a home office or something. Included are some pics. Thanks for the helpRestoring/cleaning MGC Thompson M-1921 22750710

What advise do you actually need? do you want to re-blue?

Yes I guess that would be the first step. I don’t even know if there’s a product out there that could help me restore some
Of the wood as well. Again, I have no experience at all and was just looking for suggestions. I can research the forum some more if the topic has been covered. Thanks for the help.

you can use solvol autosol or a similar product and a lot of elbow grease to remove the black on it now and the zinc can be polished up well (with effort), or a dremel with scotch brite wheels will work well. You can get a zinc blue from Japan or look up zinc black or some memebers put other coatings on as well, very much up to you on the look you want. you can get gun stock restoration kits that will bring that stock back to life or again keep that used look.
any advise on internals just ask.

Wipe it with a dry cloth, then spectacle cleaning patches or spray and then Zebrite Stove Polish.  Buff with a shoe brush and then use a clean duster.  Avoid handling it too much before it's dry. For the wood furniture use a fine sandpaper to remove dirt and scratches then use wood stain or oil to finish. Take photo's and post here.

Just found out I can access a UltraSonic gun cleaning machine. Advisable or not?

Okay fellas. Got a Birchwood Casey bluing kit and tried to blue it. Looks like crap! So disappointed. Reading that I might have to heat the upper and do several coats? I took it to a local gunsmith and despite what if read on the forum he’s said to use satin black spray paint. Any help would be appreciated

The gun blue kit is made for steel, not zinc. That's why your results are not as good as you had expected.

I got "ok" results with some diluted bluing liquid and elbow grease, but said if I ever tried it again I would setup a dip tank and try that.

Duracoat make some spray on Blue type coatings as well as Parkerising look alike coatings. I’ve had good results but surface prep is king. A fine sand blast with Aluminium Oxide is the go. I use a Badger Mini sandblasted
