Line-X Premium...any way to keep like new?

So I had to have my rear bumper resprayed after a year due to the shops fault. I had my flares done as well. Now they do not match to the front bumper. Now that it is new again, is there any way to keep it looking new/shiny?

 

you can use some 303 solution over it to keep it protected from UV.
My bumpers were done 3 years ago and they still look the same. is your truck garaged ?

 

You would think that you wouldn't need to with the cost of the premium. I do have 303 that I use on the interior, but wouldn't it streak on the exterior once it gets wet?

 

I use shine supply Clutch (I just spray and leave one) It seems to work really well on line-x.
Granted it makes is slippery, but restores the non premium to gloss, i'm sure it work on the premium stuff.
