I've read that either of these is okay for under hood black-out for a 69 but at first glance it looks like the blitz black is almost dead flat where as the 1613 is more of a semi flat. I havent actually sprayed the blitz black yet so I'm just comparing some of what has dried on the lid to some 1613 that I have sprayed.
So basically is the degree of gloss pretty much the same with these two paints or is one generally flatter than the other? Which one would be prefered for underhood black-out on a 69?

and picked up a few cans of Krylon Satin Black #451613. Now I can't say for sure if this is the same as the old 1613 but often times a company will add a prefix or suffix to their product number for various reasons and it may or may not mean that the formula has changed. I still have some of the "original" 1613 so I'll spray a comparison between it and the "new" 451613 in a few days and let you all know if I can see any difference.
