Here’s a vote for cerakote wipes. Put them on wife’s flares in October and they still look fresh. Not quite a wet look? but shinier than stock.
You have to be careful to clean everything before applying and having good lighting to make sure you get an even application because it will last a long time after it dries. I have some marks on my door handle I can’t get off because I didn’t clean well enough before applying
I only used a couple wipes per side and did all plastic trim basically.
I used 303 on my rolling hard bed topper and didn’t seem to last at all, though those are different surfaces.
So many products... so many recommendations... Which is why I often through my hands up and do nothing, interior products too, leather products too... UGH.
Having said that, this guy has a 6 month review of 25 products.
