Spraying my case insides...

post #1 of 9
Thread Starter 
Hey people of the modding forums!

Just wanted a few tips and pointers on doing some spray work. I have myself a Stacker 832. I'm happy with the Black ally panels of it. But the inner chassis is raw silver/grey aluminium. I'm looking to give it a coat or three of blue to give it a better finish.

My plan is pretty simple. strip it of my PC and water cooling loop bits. remove all the black panels/grills. Dremel the edges inside to a smoother finish( the 830/832's are notorious for their razor edged ally innards.) and give the entire chassis a lick of paint.

This is where I need the help; How would I prep the raw aluminium and what sort of spray paint should I be using on it?

Would I be correct in thinking I'll need to rub it down with alcohol cleaner to de grease it after a light sanding, and then use a flat primer? Or would just a a sanding and rub down be sufficient for it?

Thanks

I would give it a good rub down and prime it first just gives a nicer smoother finish, not that I ever paint the inside of computer cases, but my company makes aluminium signs for runways I imagine the effect is more or less the same (albeit on a far larger scale 6x1m )

be careful when your spraying to get even coverage and don't let it drip and or run, If your not sure use less to start with can be quite hard to judge until your used to the particular spray paint your using.

Ah That's a relief. I despise sanding jobs XD I don't mind using 3-4 light coats to get the even finish.
So rub down, 1-2 coats of primer, and 3-4 light coats of color.

I'm gonna be busy the next few days

Thanks for the tips

EDIT: I'll also get some pics for a work log too. get'em up in the forums

Hopefully that should be fine but It might be worth waiting a little while see what people who do computer cases say, Like I say my experience is on a somewhat larger scale ^^

Here's what I do whenever painting a case (inside or out)

1. Sand the case down with a medium / fine grit (400) sandpaper. This will knock down any small imperfections in the case and ensure everything is nice and smooth.

2. Blow the case out and off with compressed air. The sanding process will leave minor shaving dust all over the case and in the cracks.

3. Wash the case with warm soapy water (1 or 2 drops of Dawn will cover it). This will degrease the case and ensure no oils or substances are left on the metal. Let it air dry.

4. Once the case is dry, start spraying a few light coats of self etching primer.

5. Apply a few light coats of color

6. Apply a few light coats of clear coat

7. Let the case dry for 72 hours

8. Wet sand with 1500 and 2000 grit sandpaper (one or two drops of dish soap and warm water, soak the sandpaper)

9. Enjoy your awesome looking case.

* The most important thing is drying time and light coats. Don't apply too many coats too quickly. Be patient and it will look great.

I concur - I usually do 4-6 coats depending on how visable the finish is going to be and I wet sand inbetween every couple of layers. Some will say for a perfect finish you need to sand every layer with different grits, etc, etc. While that produces a great finish, it isn't always necessary for the interior IMO.

I will say etching primer is a must if it is unpainted alluminum. I've had a couple cases in the past, where I had some paint peeling issues - without the etching primer it was like spraying onto a no-stick pan.

Thanks for these tips!

I'll grab myself some more sandpaper as I only have 1200 at the moment.
I'll start gathering supplies today and start on the weekend.

I'll report back with pics and possibly get a little work log going too.
Cheers.

Painting the inside is not much of a hassle as it is the outside, I have done a few with matte black.

Just give the case a small rub then wash it up and let it dry under the sun, then use some primer and then a few coats of paint..let the paint fall in there and dont go using too much spray..

Oh and dont forget to use a decent amount of clear coat after it dries up in a couple hrs..
