Mike,
Super picture. That is a lot flatter than I would have guessed. Most older (C3) use more of a semi-flat. Looks like high-temp Rustoleum flat would do pretty good. There was so much semi-gloss on the tips and mufflers that it had thick runs in it.
As far as the stainless goes, I was just quoting the NCRS tech manual which said all 90 & 91 C4s had stainless systems. I have quite a bit of corrosion on mine, so if is stainless, they didn't break the bank buying it. I was hoping there was some type of chemical that would remove the rust without wire-wheeling or sanding.
