New hard plastic tonneau cover. Products?

I looked for an answer, but only tonneau cover questions were either for the soft type, or painted.

Getting an Undercover Elite, in hard black plastic installed Monday. Any suggestions to keep it looking good, with semi-gloss shine? I do have Solution Finish I use already, but that is alot of surface area and product. If thats best, so be it. But wouldn't mind something that is either cheaper since so much product would be used each time, or something that may go further with less?
Thank you in advance.

I would go with GRIOTS TRIM RESTORER. I have used this in the past and it's a very good product. And comes with a very good applicator. A little go's a long way. Treat it once and it will good for several months.

Wanted to add. Don't worry about the product running off on the paint when it gets wet or you wash. Never did for me.

That really makes me happy. Do you use any type of topcoat?
