Swirl painting an old external drive case. (Yes, I’m bored)

I have a 500GB passport external drive that I sometimes use.  Solid black, plastic clam style case. It looks rather nondescript all black, it is a gloss black, and over the years it has its share of light scratches. So I decided a face-lift was in order.

This is my second attempt at swirl painting. The first was okay, but the color selection was horrible, too many colors, and the word garish doesn’t even come close. It was a Wi-Fi Cantenna I built, may it never be seen again.

Inside the house:
First we removed the hard drive from the case, that was an adventure. They put those things on snug, with no visible spots to release anything holding it. I taped off the information sticker on the bottom. 

Then to keep paint out of the inside, I made some filler from foam poster board I had lying around. Folded a piece and inserted a piece of plastic coat hanger as a handle for dipping.

Outside:
We moved outside and applied a base coat of gray aluminum color enamel (all the paints are enamel spray can). After drying for a couple hours, I lightly sanded it with 2000 grit sandpaper. Then I taped the open portions sealing the foam poster board and insides. Again, there was no hard drive inside the case. 

Then I prepared my five gallon bucket by placing 3 gallons of water in it. Enough water to dip the small case in without touching the bottom. I used hot tap water, and stirred in 1.5 tbsp per gallon of borax detergent (20 mule team). Making sure It was thoroughly dissolved. I waited for the water to reach about 80F. Once this was 80F, I alternated spraying Gloss black, Aluminum gray, and Gloss White, and Blue. Alternating the amount (about 5 seconds of spraying) onto the top of the water. Each spray formed a color ring in the water. Using each can twice. I then used each can to do a 2-second spray in three areas near the bucket edge and the paint there.

Using a pencil, I slowly moved it through the paint, drawing it along into different patterns until it looked good to me. I slowly dipped the case into the water, edge on, at about a 50% angle until the entire item was submerged just below the surface. Another stick was used to move the paint just above the case away so it was clear.

NOTE: I would suggest using liquid paint, for swirling, a lot less messy with the overspray and fumes, you can then do the dipping in your garage or hobby room. There are various liquid paint brands mentioned in YouTube tutorials. You still need to use spray enamel for the base coat/primer (applied outside of course, or with PLENTY of ventilation).

I removed the case and allowed it to air dry for 30 minutes. Then I VERY gently blotted it with a paper towel to remove any large water droplets that might be clinging to the surface. 

Clearcoat: Some do some don’t. A coat of clear always brings out the details in my opinion.  I applied 3 coats of clear. One light,  two moderate, spaced 20 minutes apart.

Finished case:
For only my second try at swirl painting, I thought this one turned out much better, due to the color choices. I took several pictures to share. Each one looks different. Some under a lamp, and some with a flash. You never know how they will turn out, or what effect you will truly have. You can shoot close arranging your swirls, but there are so many variables that can occur while dipping. The paint is constantly reacting as well.

There are a couple spots on the top, where the flash illuminated some minuscule droplets of the Aluminum paint. They look like deep space stars.

Smooth or Textured
It has a slightly textured finish. Very smooth, but you can tell it’s got some soft texture, some like that, others like a smooth glossy feel.  I haven’t decided yet if I am going to do my normal buildup of the clear coat to a smooth finish, or leave it textured. What are your thoughts.

Can you see the stars in the large blue and black areas? Your imagination can really make interesting images out of the patterns.

Case bottom where the rubber feet go. You can see the soft texture that resulted. It feels good though with the clear coat on it. No hard edges to the texture. You only know if the light hits it just right, or you run your fingers over it.

Under desk lamp, no flash.

  1. I can’t say I would ever have thought of doing this, Ron. And even given your detailed ‘how to’, I doubt I ever will. But the finished result is very good indeed, so well done. 🙂
    Best wishes, Pete.

    1. Thank you, Pete. I should have done a video for it but didn’t. I will use the model paints next time, I think they are called Testor. I used them as a kid on my model cars. Thanks for the nice comment.

  2. Very nice! I long time ago, I did marbelized finished on wood and this reminds me of that. My technique was simpler and involved sponges and feathery brushes. You picked the right colors for this project. Looks very “upscale!”

    1. Thanks Kate! I remember doing the marbelizing kits in the early 70s on my furniture just married. I once did the feather duster method also on a table. Looked pretty good. I’m glad you liked the colors, I don’t know how I managed to get a good pattern, it just worked out. Thanks for the nice comment, Kate.

    1. I think the Borax helps the paint float better on the surface. I need to try it without Borax one day. Glad you liked it, I bet your Christmas ornaments were beautiful. That gave me an idea. Once before, I painted a computer case black. Then put a couple layers of clear for depth, then a very light spritz of the gold paint, then another layer of clear. The airesol droplets of gold would sparkle just like glitter.

      Thanks for the nice comment, Janis.

  3. A billion years ago when I saw Big Brother and the Holding Company at the Fillmore West they had designs like this from oil and paint on a glass pane that they shone light through. I think you may have resurrected psychedelia!

  4. Oh! Right Arm! I mean, Right On! I remember Holding Company and the psychedelic phase. Strawberry Alarm Clock and the others. Memories that were of a good time.

    Thanks for the comment, and the memories.

    1. Actually I think it’s the medicine they changed. I have suddenly started wanting to learn everything. I have burned fingers trying to solder. Taken apart everything that I could find. This was sort of relaxing. Thanks for the comment Rooster, keep an eye on your six.

  5. Thank you, Ellie! I enjoyed doing it and seeing the outcome. When it warms back up around here, I think I will start doing some simple screen printing again. I enjoyed making mousepads and t-shirts.
