Sand Blasters are AWESOME!!!

[jbd5015]

So i took the thermostat housing to the sandblaster at work today. I put some high temp ceramic paint on it, although i think its a little shiny for what i want, but ill put it on for a little and see how i like it. Im going to be sand blasting the intake manifold this spring/summer and painting it too.

Looks a lot better though. If i can find a normal silver high-temp paint ill probably use that.

Looks great!
Are you going to clear coat them?

[jbd5015]

i dont know if the high-temp needs a clear on it, probably not a bad idea, i just dont want a glossy-er finish than whats already there. I still dont know if its too much or not. The can of paint made it look like it would be more of a flatter silver, but this will work for now.

why high temp? Water temp. will reach 120°C max. and this temperature a normal paint should be able to withstand. my experience with high temp. paint is that it need very high temperature to really dry. Didi you put the part into an oven?

I did the same BTW on my 635CSiA incl. intake manifold, water pump etc. but just clear coated the sandblasted parts.

that looks awesome! What kind of blast media did you use? I think i may just blast this paint off and do that!

the nicest results you get with glass pearls, but it hardly takes off any corrosion. So if you have real dirty and corroded parts start off with corrundum and then give it a nice finish with glass pearls. The shiny parts like the springs on the throttle body, fuel rail etc. I had nickel coated after blasting them. Valve cover, filter housing and all other black parts are powder coated.

[jbd5015]

sounds good. what kind of clear are you using on those parts? spray can? Cause thats what i can use, and have been using. Im thinking of powder coating some pieces, but i want my thermostat and intake to look like what youve got. it looks awesome!

Im just going to blast it again, this blaster im using has glass bead in it right now, took the nasty stuff off pretty easy.

I bead blasted my Alpina's to remove the corrosion that was on them. They had sat outside for a long time. I used Dupli-color wheel paint,primer, and clear. They came out looking really nice for a spray can job. I now wish I hadn't used the clear actually, it has already yellowed just a bit in a couple places where I got it too heavy between the spokes. You can't see unless you look really close.

My powder coat guy has clear. I plan to send a few valve covers and intakes into him, after I blast them.

i took the paint off, ill get pictures up soon.

But what kind of clear did you use on them? Should i just use a rattle can? I want to do a matte finish instead of a glossy finish.

-Jeff

I used a spray can and the structure of the aluminum will avoid a shiny finish automatically. But matte clear is also available in rattle cans.

I couldnt find the matte finish, but the shiny clear coat came out just fine.

I guess your right on about the structure, with how many shapes are put together there on the housing, the shine didnt show up. As well as the aluminum has a sort of texture to it after being blasted, i guess the clearcoat kinda fills it in.

I've had the housing of the alternator housing clear powder coated after blasting them and this is a shiny finish. But powder coat paint is rather thick compared to wet paint and that's why. Turned the overall finish into grey BTW.

i see. I think if i went the powder coat route, it would be for colors, and it would definitely be for the valve cover. I love the look of the blasted and clear coated aluminum on the intake, doesnt get much better than that if you ask me!

I never knew there was a clear powder coat, sounds like it would be neat for some applications.

Clear powder I use on my rims to protect the polished dishes from oxidizing.
It is also used on may metallic powders.
