I have some questions about the painting process..... I bought some Krylon Fusion paints for plastic. To make the Sintra as shiny as you did in the last two steps, did you just apply many layers of spray paint, and then a layer of gloss? Or, did you take the time to sand, prime, sand, paint, sand etc.? I find Sintra has a bit of a grain to the surface.
I actually don't like the finish of the Fusion products, I've had them end up tacky after plenty of drying time on several occasions. I typically use Duplicolor.
I do wet-sanding with 800 - 2000 sanding during my process. I typically do 2-3 coats of paint in a very clean location, with a pre-sanded product. I have been doing different tests with the paint to try and get the best effect with the metallic fleck paint that I use. I think my best effects have been less sanding during the painting processes. After I get the right paint, I go right to clear coat without sanding. I do many light coats (8-10+) and at the end I sand with 2000 grit sand paper. Then I do my polish and buffing. I am still not certain on the best order in the sanding priority, it is usually trial and error for me. Sorry this isn't very clear. One of my next tutorials will be my Duplicolor / Spray can paint techniques that I use.
I tried to do research on sanding but it can be difficult to get the information you need. At Canadian Tire some people recommended starting at 220 grit, some at 800, and I just don't want to wreck it. I will try experimenting and hopefully find some success soon.
Great! I am going to try it out, starting with 800 and moving down if needed. It took so long to do the research so now I am on a time limit for my project too I am thinking of using air dry clay for the swirl detailing as I feel like using sintra (like you did) would be quite complicated...
Ah sorry I keep bugging you with messages ^-^ Do you mind also giving some tips on sanding. I assume it is best to start with an 80 grit, and move up from there. I did a few trials but the sanding makes it quite scratched up it seems.

For paint specifically, once the whole thing has been sanded smooth, I use 800 - 2000.
