I used carb cleaner on mine and had the same problem if you did not remove the carb cleaner before it dried. The only way I was able to give it a great finish was to go over the whole thing with a wire brush in the end.

that’s probably what I need to do, use a wire brush.

I've found the only way to get those castings to look factory new is a quick trip through a (glass) bead blasting cabinet. I follow up with a PPG chem-film bath (keeps the aluminum oxide corrosion at bay). I know, not everyone has these options - just my 2-cents....

Wow-that's what I'm going for Joe. Looks great! I might be able to get access to a sand blaster, would that work? Or does it need to be beads?

I love your gold paint. My 85 is the two-tone light blue/ dark blue metallic. It's still in very good shape except I have a spot of clear coat damage on the top of the rear bumper.

I cleaned my aluminum intake surfaces with a pressure washer and scrubbing with harsh green scrubbing pads and detergent. I think anything harsher will scratch the surface.

Actually, I had removed all the aluminum parts from the car during my rebuild and scrubbed them with the green scrubbing pads. It did a great job of making them look like new. It's just a lot of work.

Got my intake back together and the car running again today. Glass blasted the aluminum intake, runners, valve covers and thermostat housing. I'm really happy with how it came out, thank you for the advice everyone! I'll post more as I do more.

Looks great! You are very lucky your valve covers have such nice castings. Mine were very pitted.

There's some pitting there, but it's minor and doesn't show up in the photo

SO I am really happy with how this came out. Wanted to post another pic from drivers side.

This is makes me want to do something about the smog pump/alternator as they are much less shiny than the rest...
