The volitility of plastic (being petroleum base) can really make painting a hassle.
I have painted the face frame on Black Widow three times now. The first time I was moving too fast and applying coats on paint that was still wickingoff its VOCs..
This "trapped" the solvents in the first layers where they had no where to go except through the new paint layer and into the plastic--this created a dull fog in the candy color that took almost a week to dissipate.
Since I was still getting the hang of Candy Metallic paint I assumed that I needed to lay on more coats--this only made the fogging worse and take longer to settle.
The key to paint is patience...not the kind of patience I am used to--which is to steadily press on against a project regardless--but the kind of patience where you need to get away from the project and leave it alone
Paint is something I am really just a novice at...I am primarily a builder. But in PC Mods you need to be good at everything...sending a case out for paint to a local Autobody shop is an option...but then I have to pay them and wait for them..and if they screw up I have to hassle with them...too many variables for me.
Paintingwith spray cans is problematic too..as the kind of paint you get at WalMart or Lowes just is not good enough. No matter how well you prep the surface the paint is still tender and easy to mar. Automotive paint from a real spraygun is my next "tier" and I have the equipment..but not the proper well-ventilated and dust free environment I require.
So until that moment I compromise and use the best spray can paint I can find locally--which is Duplicolor.
Compared to Krylon or Rustoleum (the premium bombs available at WW and Lowes) Duplicolor is far superior. Once properly cured Duplicolor is nearly as tough as One stage Urethane. Duplicolor also makes the best primers for metal.
Self-etching primer is the way to go if painting aluminum or any other surface you have doubts about RE adhesion. As long as the surface is clean and free from oils and other contaminants you can skip sanding with the use of Self Etching Primer because it creates it's own mechanical bond by eating into the surface and really locking inot the substrate.
The Duplicolor Bumper Coating that I used on Black Widow is very much like self-etching primer in a black base...it locks onto the SEC chassis better rthan anything I have tried--this is important becasue the chassis inevitably get scraped and abraded when the end user starts fitting hardware. Nothing would be more annoying for a new owner of a custom case than to see little streks or bare metal here and there from sliding in Hard Drives or whatever...
Preparation is the real key to success with painwork. It only takes a few moments to quirt the piece--but it will take ten times that to get the surface ready and to prep between coats. It's not the application of paint as much as it is geting the surface free fow blemishes/contaminants/dust and keeping it taht way until the paint has cured.
If painting outside you will soon discover that insects love the smell of fresh paint--this is because many bloodsuckers use the butyl mammals give off through their skin tio track down the next meal--the VOCs from paint probably look like dinner to them.
One trick is to soak a rag in lacquer thinner or (better) toulene or acetone and tie it to something about 20 feet from where tyou are painting...they will go for the stinkier VOC and leave your work alone for a little bit...long enough usually.
I also like to move the piece shortly after I paint--the overspray attracts little gnats that then inevitably land on the fresh paint...so I move the piece into the sun--bloodsuckers generally avoid full sun--and if it is breezy it's really safe.
Hope that helps
Another plus with Duplicolor is the wide range of metallics and other specialty paints
