Garage Therapy /ONE: Tyre Serum
This has been the go-to product for my tyres for well over a year now. It leaves a lovely satin finish and has incredible durability. It’s more than just a dressing as it conditions the tyres and after the first few times of applying it, I noticed that the tires stayed much cleaner between washes and still repelled water.

Gtechniq C4 Permanent Trim Restorer
I have personally found this product to last about 12 months on my own vehicle (50 washes) and did a great job at restoring the black plastics. It isn’t the cheapest option, but it is straight-forward to apply and since it lasts so long, there’s no need to reapply it every wash like with most trim dressing.
