Nate, your method is pretty darn good. I will add though you should be using flex additive in the paint.
After owning a body shop my entire life I can tell you we always use it on bumpers, moldings etc..

Depends what you're using. I do all of my custom stuff with House of Kolor, and for th eurethanes, it's not necessary. There is also a large difference in the plastics that bumpers and automotive mouldings are made of than sled panels. Most automotive plastics are are TPO, which is more flexible, and contains olefin, which needs other additives. Sled plastics are far more durable, (less flexible) and made of different materials, so you have to know what you're spraying on before you chose your materials.
Using a flex agent when not necessary actually makes the paint job more suseptible to damage. I do have a few other tricks that I use when doing sleds, many have been learned from trial and error on my own over the years, but I can't give away all my secrets!

Now don't be stingy, we want them all! lol
House of Colors is pretty much polyurethane and urethane now. Pretty
flexible out of the pot. Little expensive for production work. Sikkens is by
far the toughest most durable paint in the modern market place.Their base coats can be a pain to work with as they are hot and tend to lift. I still
would use a flex additive. Had many a bumper come back destroyed in
another accident with the paint still on it. Without the flex the paint splinters
and pops off. Never saw any degradation of the paint from flex agent, only
in the finish. A little tougher to spray and doesn't cut and buff quite as well.
The bumpers have moved completely away from urethanes now and are a
composite plastic that is tougher and finishes nicer. Also recycles much better.
But I've been retired for 10 years and things change. I've only sprayed dupont since then and it definitely needs all the help it can get.
