Great work! The S4 looks great. The video is excellent, and look forward to a build video!
If you don't mind sharing the info, I'd love to know what powder coating you're using, as I've personally been finding powder coating to be far less scratch resistant than anodizing. I've tried textured, but not wrinkles though.
The mix is custom, so I couldn't help you there. I can suggest this particular mix from
Prismatic. It is pretty tough and looks great.
Powdercoating (like regular painting I guess) is reliant on so many different things to achieve desired results. The powder itself (crucial), the preparation of the parts, the chemicals used to clean it, the prebaking process, the application, reducing air swirl in the oven, the final bake, and the setting. If you get one of those things wrong, you get a bad result.
The people I use for my custom powdercoat jobs are MASTERS of their art, and they changed my mind about what can and can't be done with this process. They do show-cars for Cruisin The Coast, U.S. Navy projects, and even apply the C.A.R.C. to the local military vehicles as a powdercoat now...which in addition to being resistant to certain wavelengths is about as durable as you can get in a coating. The people who do the powdercoat for my manufacturers worked with me to get the powder mixed right and it took several tries. It isn't as bulletproof as the stuff used for my green "show" S4 with the heavy wrinkle, but it is very durable. I call this one "
Prismatic Basalt" and it is very durable in addition to being immune from oily fingerprints.
This one I call "
Paladin Black" and it is another special mix and it is the most durable mix I have achieved--strong enough for Jeep Bumpers! It is also immune to fingerprints.
Here is a glimpse on a special project I have been working on, that uses a mix between the
Paladin Black and the coating used on the retail version of the S4 Mini. It has a softer texture than the last two, but the specularity of the flakes make fingerprints nearly invisible:
I like this picture because it shows the luminosity of the paint with the evening sun reflection. This was very close to how I wanted the S4, but I wanted to bring up the "flakes" a bit more in the S4 and reduce the specularity even further.
Here is the final mix:
I haven't destroyed this sample yet to test its durability, but I have done basic everyday use tests. It is not fingerprint proof like the other mixes which I am bummed about but I think this is as flat black as I can possibly get. My white background images look like I tampered with the saturation, but I did not. I have a high-end Bowens head with superb color rendering and all Bowens reflectors and silks so there isn't color perversion (blue or yellow tinting you get with cheap silks and reflectors).
Also, I noticed someone was asking about power input mounting. In case you haven't already, note that the HDPLEX mounting is holes are 20 mm apart and use M3 screws (versus 19 mm apart and M2.5 for the PicoPSU Mini DIN connector).
I need to make it clearer on the preorder page:
Thanks for the comments and questions!
