Machinery gray spray paint

[PT Doc]

I need to repaint a Kalamazoo 3hp 6x48" belt sander. I'm excited that this is a USA made grinder with a USA Baldor motor. The safety shields will be a black hammertone. I chose this simply because of ease of touching up when I bang things up. Not if but when.

The stand will be a dark machinery gray by Rustoleum. I think that it is gloss though. I want to paint the frame of the grinder a lighter gray since that is the way it was.

The Baldor motor will be a medium charcoal gray although Baldor has no cans of this exact paint in the country. I think they use 2 other gray motor paints so I will likely go with that.

Do you like flat satin or gloss when painting machinery?

I greatly appreciate your help. Thanks

Satin.

Satin if that's the only way a color I like comes. Then I gloss clear it.

 

[PT Doc]

Sounds like gloss is the way to go? Easier for clean up? Satin will get a shiny spot with scuffed hard?

 

[gilbo]

flat satin

Gloss because it cleans up better. I use Tractor Enamel Paint from Valspar with great results on a CNC Router table and a Bridgeport M-head.

Gloss gray rustoleum worked very well for my recent baldor grinder resto.

I use machine grey rustoleum too - looks great on the craftsman 150 DP I'm working on

I use Dupli-Color gloss machine gray and like the results.

You say that there are no cans of matching paint in the country? How old is the motor?

The grinder might be 10 years old. Baldor might have changed to a different gray. I don't know the details, I just called and gave then the spec number and she looked up the paint code and then said there were none in the country. I'll just use some other grey, preferably a baldor color.

Here is some interesting information that was posted by Dave Kamp on practical machinist about gray paint:

Just a silly historical tidbit...

There is no coincidence that Machinery Grey paint is similar to Navy grey paint.

Prior to WW1, machines were typically sent out with whatever type of coating the manufacturer could use to reduce oxidation.... paint wasn't so common.

February 6, 1922 marks the signing of the Five Power Naval Limitation Treaty, aka "Five Power Treaty" or "Washington Naval Treaty", under which naval disarmament took place between US, UK, Japan, France, and Italy.

This treaty was the incipent force of an economic 'shock wave' that struck all the affected countries- it put millions out-of-work... starting with shipyards, and steel mills, railroads, and materials suppliers... working it's way down through the economies of all countries.

The other affect, is that many materials previously slated for warship production, went to surplus markets. Grey paint was one of those materials.

Lots of machine tool manufacturers bought grey paint at a substantial discount as a result... and (pun intended)... it 'stuck'...

Hammered gray is my weapon of choice.

I also think gloss will clean more easily

I used the dark machinery gray Rustoleum and in my opinions is not dark at all. Ended up getting a different gray from Rustoleum, not professional, that will likely be the color that I want.

 

[PT Doc]

I ended up getting 2 cans of Rustoleum charcoal gray # 7784 that I will use for the stand of this grinder. The professional dark machinery gray will stay on the frame. Those professional cans are pretty nice to use though. The dark machinery gray is just not really dark in my opinion.

Having used most all "Machinery Grays", IMHO Plasticote T10 is the flat out best. Very nice darker blue gray that is very easy to work with, dries fast, and you can recoat at any time. Matches well to OEM 40's Delta Rockwell.

Any photos?

is all this Rustoleum gray you guys are using SPRAY or BRUSH?

I need to do a Baldor buffer and stand tomorrow and can't imagine brushing it would look good....

Gloss cleans better, but i prefer the satin look,

I painted a Craftsman DP looked just like the same color dark gray that was on the older CM crown logo 150 model the charcoal gray from Rusto was spot on

You're correct, the Rustoleum Professional Dark Machinery Gray is not very dark; however, a few years ago (maybe 5+) Rustoleum also sold a Light Machinery Gray that was, indeed, very light (don't remember the paint code number). So, in comparison to the Light Machinery Gray, the Dark Machinery Gray was noticeably darker. I haven't seen the Professional Light Machinery Gray for sale for quite some time so maybe Rustoleum no longer produces it.

I use the Rustoleum Dark Machinery Gray for many applications and like the gloss finish.

Rustomleum Dark Machinery Grey:

Wish it was darker, and less glossy.

I went with it, because it was readily available.

I've been using the Rustoleum Smoke Grey...
