Thanks CyberJack, I always had in the back of my mind to replicate the wrinkle finish. As you said no one has attempted it so I was winging it and to be honest the can in the picture was my second can and I had to strip back the first attempt as the finish was not how I Invisioned it to look nor did it match the original paint on the back of the chain case. I followed the directions on the spray can and the results were great if you were painting a valve cover on an engine but not a chain case for a SB. The first results I got turned out to look more charcoal with a rough texture like sandpaper or a grinding stone with a Matt metallic rock look. The way I over came this to get a more smooth black satin finish was to do lighter coats with a short mist spray and a flick of the wrist rather than a heavy sweep (as instructed on the can). I only did 2 light cross hatch passes after waiting 5minutes between coats then allowed the paint to almost dry but still be wet and smooth. The secret is then to heat the finish so it wrinkles but a heat gun or my baking oven is to hot for this finish look so a hair dryer that's not to hot is the key and to make sure you let the paint craze rather than crinkle so its not to rough and the paint has that satin smooth look (remember the wetter the coat the rougher the crinkles so let it dry a bit). It's not easy to get the finish I wanted, I made it up as I went along as I said i had to buy another can and re-strip the first attempt. It's also important not to spray on a hot day as the paint will crinkle while you watch it with the heat of the sun ,best to do it in the shade either early in the morning or afternoon/night (better still during winter) as the paint will stay smooth and dry out slowly untill your ready to heat it to the finish you want.
Below is the first attempt that looks like and feels like a grinding disc that was baked in the oven as instructed from the can label, the second pic is my attempt that's more of a smother black that has a leather/vinyl craze look.
