I must have asked numerous times on numerous forums how this is done. Did you ever take a
close look at the paint on a 5150 or 5170 (or hell even any IBM monitors that are age
appropriate, but those aren't metal). Did you notive the wormy, orange pealy finish. I
don't think anyone has seriously attempted to explain how to accomplish that. It's
not simply a sligjtly gritty texture as in the case of modern atx cases, that can be done
with a spray can, sort of.
Do they simply cause the spray gun to spit on the final coat, perhaps while the previous
coat is still tacky?

Chris,
I don't know specifically about the IBM PC, but I think what you're
describing is powder coating.

Powder coating is just a durable finish. It can be textured or flat.
Polane and Raptor are urethenes. Usually catalyzed.

You'll want to be using a supplied air system to safely spray a 2K.
2:15 p.m.
So this polane stuff creates the texture when used with any airgun? Everything I have is
small, not ideal for painting a car, but more then adequate for covering a 5170 case.
Artist equipment. And I have a somewhat larger gun that has a gravity fed canister that
can hold upwards of 4oz. of paint. The compressors I have can go from 20 to maybe 120psi
iinm.
The question is can this polane stuff be had in small quantities. And in the color I
want.
What's a 2K?
2:33 p.m.
Have you ever tried to fix textured drywall or lathe/plaster? It's always
down to playing with various settings and trial/error if you want to match
a specific finish. These coatings facilitate a texture but they won't do
it for you. If you apply at a high pressure they're not going to do
anything. You can spray Raptor flat if you so wish. I think you
may be able to get Raptor in a quart but Polane is likely a gallon. Plus
the hardener. Then you get into color. You'll need to have your local
industrial finish shop tint based on your codes or apply a compatible
(color) topcoat, emphasis on compatible. Then you get into application,
you're usually applying at a low pressure, wider tip if you want to get a
textured finish. I doubt your setup is this. 2K is 2-part catalyzed.

Ok I'll stick with rustoleum then. I'll attempt to mimic the original texture
even if not so perfect.

On the same subject, but slightly off topic, whatever happened to the
"wrinkle finish" (I think that's what it was called) that you'd often
see on old panels?
My recollection is that it was a baked-in process that resulted in a
very tough finish. I've got at least one toolbox done this way.

Chuck,
You can buy that in a spray can at the hardware store. I've used it before
for some of the replicas I've built. It works great.

If you can achieve a textured finish using a rattle can you're a better man
than I!

I won't claim to be a better man than you, but,
45 some years ago, there were rattle cans of "krinkle finish" sold in auto
parts stores. Looked OK for valve covers.

A wrinkle finish isn't what I thought this was about. Plus gotta find it
in the color you want, or top coat with something compatible.
Very hard to achieve a finish like polane out of a rattle can.

True.
But, some "textured finish" from a "rattle can" is possible. Just not
the
right textures, nor colors, for the current need. Although, if you go to
the specialty stores in 1977, you could ask them what else was available,
. . .
4:26 p.m.
You all aren't referring to that hammered look?
And regarding a textured finish, I have a cheapo Raidmax atx case I got from Newegg about
4 years ago. 12.09$ after the rebate. Shipped. It and other cases I've bought in the
last few years all seem to habe that slightly gritty appearance. Sellam and others said
powder coating could be a possibility. But I don't understand how that could be done
economically. Regardless the village boob was playing around with a spray can one day. And
if you know nothing about spraying canned paint, you need to apply as many coats as
possible, thereby achieving nice even coverage, and avoid the drips. After 1 coat I saw a
sililar gritty finish to the atx case, but the "beads" of paint were larger. So
maybe just maybe these things are painted with a finer tipped airgun. When I try it
I'll report back.
As for painting a 5170 case, I'll apply the final 2 coats perhaps at an angle, and
adjuat the nosel so it sneezes all over the thing. Again we'll see.

No, hammertone is something else. What I'm talking about is the finish
that you'd often see rack panels (I do have a blank in hammertone,
however)., usually black. Kennedy toolboxes (maybe still do) had a
rough finish like that.
There's also a finish you'd often see in car trunks--"spatter coat"--a
textured finish with multicolored globs of paint. That *is* possible
with a rattle can.

Yes, I've used it, though I've forgotten the application and can't remember
how it turned out. It was a long while ago.

You used to see the wrinkle coat in black on all manner of WWII military
electronics. Some examples here:

Traditionally Polane was used. (Sherwin Williams)
Raptor is similar. I had a long discussion with their rep along the
lines of "ok, but how much is the paint and how much is the application".
It turns out it's a bit of both.
Obviously you're not going to get texture with a very high pressure
applicator.
