Read the first few posts, he is not gonna reveal it until he knows for sure if it is going to work, and to make sure it isn't gonna chip off or emit toxic fumes.

Rogers, as already stated, I'm not revealing it.

However, why on earth would I want to use a finish designed to prevent rust in ferrous metals on aluminum?

Chase..I had a 96 that was also coated and didn't seem to have been rebuilt at any point. Might have been a change over year.

My 1996 riviera has the same paint on the supercharger as the m62s... Must be a 96 only thing.

The points of this topic were/are:

1. Painting is bad.
2. However, I found something that responds well and works better even OVER the OEM coating.

And became (which is fine)

3. Why Eaton may have stopped using it.

Some 96'* may have come with the earlier coatings. I haven't had a chance to strip the coating on one half of my scrappy housing, but I might soon. It would be interesting.

The major point to be taken here is that had I painted the whole supercharger, and compared it to an identical unit, the differences would have been more pronounced. I think my mystery coating was partially affected by the heat of the adjacent OEM coating test area.

I just don't want everyone jumping on it until I know how it holds up.

The point to take away from this is that had I painted the whole 'charger with the engine paint (and I chose black to give the benefit of the doubt, all other colors would have been worse), it would have been far worse. Anyone wanting to win an award for a pretty engine shoud go ahead and do what they want to, but anyone wanting performance shouldn't even consider painting for now. I hope to know soon.

The good news is that greyhare and I (and Linda, who I 'gooped' in my supercharger page ejecting needle bearings) abused that mystery paint at lunch today. It held up very well. Well enough for me to commit to painting my next 'hybrid' M62 with it.

Painting, powdercoating, and anodizing should be discouraged. Polishing as well, but to a lesser extent (I assume).

if I was going to do anything I'd go polished, however not for speed, for looks.

Good opportunity for someone to lowball on a supercharger, then strip the paint off.
