Thanks all for the suggestions. The color of my '03 Expedition is Arizona Beige and the color of the plastic bumpers and lower door panels is GREY. The rubber window trim and plastic side-view mirror housings are BLACK. I read posts on various forums over several days and watched many videos. I decided to go with the Solution Finish products to restore the color. I ordered a 12 oz bottle of Solution Finish Fusion GREY and Solution Finish BLACK.
The BLACK arrived first so I started with the mirror housings and window trim.
Black Rubber Window Trim
I park my car outside and the window trim rubber had spots and was heavily oxidized. I first washed and dried the car. Then using painters tape, I taped off the glass and paint around the trim. I mixed a 50 / 50 solution of white vinegar and water in a bowl. I purchased an 8-pack of Mr. Clean Magic Eraser sheets. I gloved up, cut the Magic Eraser sheets in half and quarters, dipped them in the solution and used the sheets like a very mild sandpaper to clean the oxidation. Afterwards I wiped off the trim surfaces with alcohol. After that dried, I applied the BLACK Solution Finish Trim Restorer according to the directions (wipe on with an applicator. Wait a few minutes and wipe off with a microfiber cloth). It looked ALOT better than before I started. Once rubber starts to degrade I don't think it'll ever restore back to 100%.
Black Side-View Mirror Housings
I used painters tape to mask and protect the paint finish where the housing meets the car. On the underside of the mirror, I also masked the clear plastic light lens cover. The car was already clean and dry from washing. So, I gloved up and wiped the plastic down with alcohol. After that dried, I applied the BLACK Solution Finish Trim Restorer according to the directions (wipe on with an applicator. Wait a few minutes and wipe off with a microfiber cloth). I used a 1" disposable foam brush to get the Solution Finish into the nooks and crannies. I'm really impressed with how this turned out as the mirror housing looks like new.
After Care
I listened to a podcast of the Solution Finish product line founder. He recommended using a spray-on product for after care - Meguiar's D4510 Plastic & Vinyl Coating. It doesn't require masking. I'll look for it at my local Auto Parts store.
I'm going to continue to work on all the black plastic surfaces and then the start on grey ones (bumpers and lower door panels) when the GREY product arrives.
Anyway, I hope others may find these details helpful.
