I have a aluminum intake that I'm going to bead blast, then clear coat, the reason I'm doing it is for ease of cleaning and hopefully to make it look better. Wanting to know if anyone has done this and what kind of results they got wheather it turned yellow or had trouble with it peeling off.

I have done this quit a bit. Several motors small and big block. It looks very good, and is easy to clean. Seems to resit gas, water pretty well. Did have a small anifreeze leak that I waited several months to fix and it stained it a small amout. I have always sandblasted to a even look and then cleared. Hope this helps.

I would powder coat also. It seems as if the clear paint always turns brown.
On a side note, you should never bead blast any area that will come in contact with oil or gas. The aluminum traps the abrasive and eventually after a couple of heat cycles the abrasive falls out of the pores and ends up in your engine.
It's equivalent to dumping sand or glass down inside of your oil filler cap.
I work for a high performance engine shop and we NEVER glass bead the insides of valve covers or intake manifolds.....

Guys, i was recommended the clear satin finish by VHT. you can find this line of paint (VHT, which probably stands for Very Hight Tem) as it is a hight temp clear coat paint) at O'reillys, etc. I was recommended this product by Edelbrock.

utfball -i think most people want to have a long term solution to keeping the intake clean and neat looking. Taking it off and blasting wouldn't be a solution for me. Especially if what uncle-stosh says is true. sand /beads in an engine = death.

intake...
Do you really want to powdercoat your intake a dark color???
Think about it...what is the best state for the air charge to be in when
it starts to mix with fuel???
What would a dark colored intake add to that air charge?
Why do you think Air Gap intakes are selling so well?
I still can't believe "someone' is marketing a "Nascar" intake that is
powdercoated black...
Just my thoughts...

I can feel your need to clear coat. If Elderbrock recommends it it's probably pretty good stuff. Also POR-15 makes a highheat paint that will work too. Along with PPG.
The powder coat is good but your reaching the curing temp at times when you shut it down. The ceremec coat is better for high heat like used on exhaust. Instead of bead blasting, try some coil cleaner used on AC condensers. This is a foaming cleaner is designed to remove the oxidation on AL.

Powdercoating would stand up better I think. I had the upper portion of my 5.8 intake powdercoated 8 years ago and it still looks good, it's on the right in the pic below... it's a bit greasy in this pic but that easily wipes off.
Because this worked out so well I had my complete Typhoon intake(both upper and lower) powdercoated black.. I don't think the color will make that much difference under the hood and out of direct sunlight. Incidentially the place I had this work done told me they now have clear powdercoat as well.
