I just wanted to add my results too.
These VC's are off a '92 as well. They'll be going on my '91 bronco when the motor is finished being built.
Here's what I started with.
I cleaned them up with some easy-off.
Then I sprayed a couple coats of the duplicolor DE1650.
They're not perfect, but I think they look a hell of alot better than they did.
I wanted to use the same paint, on my TFS intake, but I ran into a problem with the powder coat, that was on there from the previous owner.
I was told not to use Easy-Off, b/c it was too harsh for aluminum. I was pointed in the direction of aircraft stripper. I gave that a shot, and it did lift the powder coat, but it turned it into a gummy mess. Basically it made things worse.
Is there another off the shelf product I can use, or am I better off getting it sand blasted?
Sorry for the hijack.
