Intake/Gasket Surface Prep
Getting ready to have intakes powder coated ('86 box intake). I know I need to degrease, wash etc. Couple of questions:
First - Should all paint be removed first from the outside, even if not chipping in places?
Second - What is a good/effective degreasing method?
Third and most important - the gasket surfaces have old gasket material and glue on them - what is best way to remove without scoring the surfaces?
I will have the powder coat vendor bead blast the parts afterwards. I will also mask off all openings, as I don't want to disturb the painted internal surfaces (or should I care?)...Thnx

Ed-
Before doing any prep yourself, ask your PC guy whether they can do all the prep (degrease, strip/media blast, clean up gasket surfaces, bake/outgas, mask, etc) for you. I did NOTHING to my S4 intake before dropping it off at the powder coater, it was a disgusting greasy mess. They did everything for the prep work, and although it's only been 3 months or so I presume they did their due diligence because mine looks great, the gasket surfaces all seal ok, and there's no evidence of outgassing or bubbling of the powdercoat (yet?!?). I did make sure to blow it out thoroughly with compressed air to remove residual media (not that I found any), and I had to R&R the flappy bearings after the fact (not an issue for you).
If they do want you to prep it, or it's a lot cheaper if you prep it, that's a different story...... 8)

Let them prep it. This way if something goes wrong afterwards, you can not be blamed for it and I'm sure they know how to prep it the right way.

Hi Ed:
Who are you planning to use? I'm doing that as one of my winter projects.
Are you doing the cam covers also? Not that you can really see them on our cars, but I figured WYAIT why not.

i was thinking about doing the same thing to my intakes however this thought also crossed my mind the local powder coating shop does chrome plating as well i wonder how that would look if they were all done in chrome? i'm not sure how hot they get so unsure of which way to turn but im sure that either way they would still look nice

There is a shop just north of the city that I have talked to...need to investigate it more and see what the price is. I'm not going to do the cam covers, as I just had the gaskets replaced last fall, and I don't want to rip that all out again. Not looking for concourse quality, just a nice look with the hood open at the local car cruises....
