Intake cleaning, silicon contamination?
I was reading on hear about cases of intakes being media blasted and causing engine damage! Given that I just had mine done, what the best way to clean out the intakes to avoid this!

I used a long flexible a/c / vent cleaning brush and a hose, seemed to the job. The brush is about two foot long with cone shape to it and flexible, it was purchased from ACE.
I did this twice despite having the intake washed by the soda blasters after blasting. No media or dirt came out.

I filled my laundry tub with water and submerged it, brushed it and I got it all out. Then after it dried I blew it out with compressed air (nothing came out). Mine was done with glass beads so I had to be really careful!

The runners clean out fairly easy, but the plenums are a bitch with the internal bell-mouths. I did the above by flushing with water, then mineral spirits, then more water, and a rinse and repeat...

I used a toilet brush. The brush end was about 1/2 wider than the bell mouth..so worked nice, long flexible handle..worked well.
Scrubbed nicely.
I DID get some black sandy residue out of mine...yessir, I certainly _did_.

Not to get off topic... BUT... what is the down side of prepping & painting the exterior without all the bead-blasting, cleaning, drying, baking, cleaning, drying & baking...??? 
I'm torn... I like the powder-coating, but have seen some nice paint jobs... Does paint hold up as well if using the proper paint... caliper paint, etc...??? Insights, comments, advise & opinions appreciated

Insights, comments, advise & opinions appreciated The alloy, without cleaning, will be so incredibly oxidized and oil soaked..that it would be a disaster to try to paint/coat it without it.
