Dlux is good but its kind of a pain to apply with all the prep work that's involved. I think Swanicyouth did a head to head against C4 and Dlux was the clear winner in regards to durability.
I found those foam paint brushes made for a good applicator. Be careful not to get any on paint or mirrors or glass. Might be a good idea to tape off those areas cause it's a pain to remove afterwords.
I did a comparison between DLux and the Wolf's trim "coating". The Wolf's stuff lasted like a wash or two - but DLux is still going strong til this day - just about a year later. It beads like day one - super tight circular beads. Prep was identical. Honestly, the DLux doesn't appear to have faded at all - and this car was driven through snow, salt, ice, & mud daily all winter.
I only use DLux now. Only problem is - it lasts so long, you may never finish a bottle.
Prep is the key. I find Tuff Shine tire cleaner a unique product - since it's designed to remove dressing / silicone out of porous rubber - it works even better on plastics. This is what I use to get previously dressed trim pieces 100% dressing free and clean.
I contribute part of my DLux success to this prep process.
If you have been using dressings with any frequency on any rubbery plastic trim and want to use a trim coating on it - it can be difficult (depending on the "plastic") to get all the dressing out/off. IMHO APC / IPA is no where near sufficient to remove old dressings from most plastics.
Here you can see the DLux on my BMW. This was taken in April or so - about 9 mos after it was applied. Here it was applied to the cowl, wiper backs, wiper parts, & wiper arms:
