As for wheels, painted, or chome, I have had good luck. For painted or clear coated wheels DLX is tough to beat and never had issues.
Bot on plastics, particularly textured plastics, DLX looks beautiful upon initial installation, and it lasts a pretty long time too.
But when it starts to wear off with time, the surfaces, black in my case, no longer look jet black anymore. They start to appear a bit greyish, and as many have mentioned, there's basically now no way to remove this product.
While the product may be still present at this point, and still protecting somewhat, the cosmetic appearance does start to look less than good IMO.
About the only way one might rectify and lessen this greying, is the use of some restorative product that contains a dye. Solution Finish might be one, and I'm sure there's some others.
Just wanted to mention this, just in case you were to do a customer's vehicle, and 6-9 months later they are contacting you and asking you what happened, and what can be done? You will have a problem at that point in time.
Thus, I might look towards another plastic protectant product, and although such might not last as long, at least you won't have such issues to deal with.
