without being cleared you are seeing the finish of the base so very difficult to tell how black something is. the cloudiness can go away once its cleared BUT i have no doubt that your results were correct in that the chroma is a much higher quality than the nason. the real test for any black is to #1 clear it so you can get some clarity there. let it dry then shine a sun gun or a flashlight on it from just a few inched away. you will instantly see how black, cloudy, brown, etc it is. it all comes down to the quality of the black pigment used.

i always do bc/cc for black. i only use ss for accessories and parts. there is really nothing to be gained other than excessive urethane wave by doing a ss with a clearcoat over. it may be a little more durable but that would be hard to prove. if your going to do ss then do ss. if your going to do a bc/cc then use bc. not sure why but in direct sun the spi black bc is a little blacker than the ss.

I looked through the older posts before with anything about black paint, always a difference of opinions. Shine seemed to think that ss only looked purer than bb/cc. Some seemed to think that bc had a hint weaker of a bond than ss for chip resistance. Main reason I ever tried ss in the first place was to have more actual depth of paint color for the personal vehicle since I seem to get a lot of scratches & chips to try & hide some of between painting sessions.
But since I just ordered a gal of ss last week, I'll try it alone first. Would you think it may be more durable than a chromabase clear from 1998?
 
Jl, chipping is a result of poor adhesion. Ss is a little more forgiving in that area but if your primer is prepped right, epoxy seal, cat your base then there is no reason bc wont be extremely durable and chip resistant. Ss black vs bc/cc black is really just personal prefrence. Ss does have a different look but its so slight that only a trained eye would see it.

The only differance I feel to what you said is when using a SS compared to BS is the mill thickness. The additional mill thickness provided from SS then clear will assist in cushioning the impact from a stone. If you were to just seal and paint a new panel it would be more likely to chip compared to building a quality barrier between the hard steel and top coat. I think there is a slightly better resistance to damage when SS and clear used to just BC.
 
Pretty much what I thought, just marginal differences between the different finishes. Some type of brown colored sealer [DuPont?] I used over epoxy, before basecoat, might actually be the weak link for chip resistance on my personal vehicle.




Now if I could just figure out where some of these damn scratches keep coming from????
 
This is a little off topic, but chipping also has to do with how brittle the product is. Given two products with equal adhesion properties, the more flexible or "rubbery" coating will chip less.
