Anybody ever use solution finish for the exterior trim?
Yes. A couple things:
1. It does not work very well on smooth plastics
2. On textured plastics it leaves a very wet looking dark black finish.
3. Durability isn't as long as I expected.
4. It works on very faded plastic
5. Durability can be increased by topping with a trim sealant like UTTG.
6. It can take a very long time to dry
7. It's not a permanent fix, but it does leave a nice finish IMHO.
I'm currently testing it on the textured plastic on my running boards. It seems to be doing well. Looks excellent IMHO. It washed away on the smooth plastic on my roof rack after the very first wash. Roof rack parts WERE removed and scrubbed with APC, then rinsed with IPA and blown dry, so they were 100% clean, so failure can't be blamed on prep.
Here are some pics on my running boards. Car is unwashed when I took these (now). It's about a week old and looks dark and wet.
However, its dry to the touch:
The thing is, it looks so good, I no longer step on the running boards to get in the truck. SF made getting in and out of my Pathy a PITA.
