For the tyres & plastic trim (exterior) I'd suggest Megs Endurance gel....
For the wheels, just use the wolfgang sealant & a layer of Dodo.....
Black WOW is the best product I have ever used, damned expensive but it seems to last forever, brought many a piece of weathered grey plastic back to a gleaming black finish
black shoe polish the one in the bottle with the sponge on the top
I put Chemical Guys bumper Gel on mine. it really is very good, beads and lasts a good while. plus you get a nice aplicator with it
through my experiance of panel beating you dont need back to black to bring faded bumpers back to life!
all you need is a hot air gun, hold the gun about 2-3inches away from the bumper and just run over it carefuly bit by bit and they will start returning to go black again! but mask off the edge of the painted parts as if you go to close you will melt the paint!
this aint no bulls**t i made up as it really does work and it lasts alot longer too!
as i said try it but be very carefull not to melt your bumpers!
