Need suggestions for painting aluminum?
KG
hits on how to chemically etch the cover & cleaning it, but this is just a home project to paint it
an aluminum color. The cover is on a show car so it will not see much bad weather. I'm looking
for a method that can be easily done at home at a reasonable cost. Any realistic suggestions would
be appreciated.

Bead blast, zinc chromate primer, any paint you like on top of that.
The paints are available in spray cans.

I'd clean it thoroughly, using a scotchbrite pad to scuff it up, then
dry it and rinse with lacquer thinner. Put it on a lazy susan and
spray away with your aluminum rattle can after a really good shaking.
It takes a lot to mix the metallic paints well in a can.
MexiChrome, as they used to call it in SoCal. ;)

Have you found any good (and non-manual) way to shake a can?
I've bungeed cans of insulating foam to a small shaker table
(from a closed Fair-Rite factory, where it was used to shake
bubbles out of potted products) but think it didn't work
particularly well. Any ideas?
Also have a vibrator/tumbler* that might work better,
especially if I make a can-holding bracket that bolts on
in place of the bowl. Probably will try that next.

I've had very good results preheating aluminum parts to 150 degrees or
so before a rather heavy coat of Krylon. The result is almost
indestructible.

BLOODY 'ELL, boy. Get some _exercise_, whydoncha? ;)
If you're using so many rattle cans per week, you should definitely
think about moving up in the world to an actual HVLP spray rig. The
savings in paint costs will pay for it quickly. Your product will
look a lot better, too, I imagine.
>Also have a vibrator/tumbler* that might work better,
I don't think it would. I've found that vertical shaking worked better
to shake up the contents of rattle cans. Send that ball from the
bottom of the can to the top and back again 100+ times and you have a
fairly well mixed paint. It gets quicker the better mixed it is, as
the sludgy solids stir up into the liquid.

Yeah, but the cleanup is a PITA

I can see a lathe or mill attachment here, much like a shaper head.

Let me get this straight: you want to paint an Aluminum housing to look

Why not simply polish the thing - that way you won't have any paint
expenses at all!

A couple of years ago there was a thread about shaking rattle cans & I
felt inspired to make this:
http://home.comcast.net/~bobengelhardt/PaintShaker.jpg
It was mostly in a Monty Python spirit that I did it (i.e., just being
silly), but it's actually pretty useful. 10 seconds on that baby throws
the ball around a lot!

I have a spray rig, which I use more often than paint in rattle cans. What
I want to shake isn't paint, but an assembly like that shown in picture at
<http://www.industrialinsulation.com/fireblock_spray_foam.htm>.
Weight is around 3 pounds when a 24-oz can is attached to a foam gun
like <http://photos.tradeholding.com/attach/hash141/21901/505.jpg>.
The can can stay on the gun until used up, with up to 30 days
between uses, although I usually use up a can in less than a week.

Prolly so ~ but I'll try anyway

I'd forgotten about that thread - thanks for the reminder.
I don't have a saber saw like that one but I could make an
adapter for my reciprocating saw (Sawzall look-alike) which
has, conveniently, a wide-range speed adjustment on it.
Thanks!

Don't paint it. Polish it and hit it with a clear coat.
If you really want to paint it. I would probably toss it in the oven for
a couple hours to out-gas it and drive out any oil/crud in the aluminum.
Then use a soda blaster to clean and etch it. Then a coat of etching
primer, and a coat of good paint.

The main thing that I have to say is *never* use a mechanical
shaker on an aluminum paint.
It builds up a lot of heat from the aluminum particles rubbing
against each other and results in bursting the can (at least for normal
pop-top paint cans) and spraying paint all over. This happened in a
hardware store where a friend worked for a while. He says that he wasn't
the one who set it up. :-)
I think that I remember someone here making a mount for holding
the base of a rattle can on something like a sabre saw blade mount.
Perhaps he will speak up (or has already done so.)
Enjoy,
DoN.

You're right, Steve. For a show car, polishing and clearcoating is a
much better idea than MexiChroming.

Yep - the black cup is the bottom of a 14 oz propane cylinder, it's a
loose fit for the rattle can. The button is a variable speed trigger -
I generally don't run it full speed.
