Ok, well, I'm not going to call the Preval system "crap", but I will say that I wasn't sure if I could actually finish my cover. So the problem is that once you insert the aerosol sprayer can, you can't tilt the whole thing by more than 45 degrees from vertical. Because there's an opening where the can connects to the jar below, and paint can splash out. The aerosol needs that hole for intake air. In my case, I tried to keep it as vertical as possible, but the paint was still splashing out from below like crazy. My hands were all blue, and this is what the sprayer is like now:

BUT it did spray very smoothly when the paint actually came out. So I finished the cover with some effort. I'll probably use another aerosol sprayer in the future for this, although... this is very messy business, and I can't say that I like it. But it's the only way for me to mix a custom color at the moment.
Now on to the cover--I'm very happy with how it came out!! It's drying at the moment, and I am considering adding an iridescent clear gloss over it. The result is very much like slightly aqua sky blue with a gold and white pearl sheen, depending on angle. Almost looks like anodized sky blue aluminum from some angles. I'll have to take better photos outside when it's all finished.


I was going to take a photo of my blue hands... but you don't need to see that

Suffice to say, I need to get a stronger cleaner than alcohol and nail polish remover

P.S.: For that cover so far:
* Base: DupliColor Adhesion Promoter, Rust-Oleum Painter's Touch Aqua (light aqua)
* Top: multiple layers of my pearl aqua concoction
* Clear coat: undecided! Probably DupliColor Effex.
