GatorBak Bunk Cover Kits

I’m looking at these to recover my bunks this fall or in the spring. I know in a previous thread a couple people mentioned using them. MrPike said he didn’t like them. Just looking for opinions and what people have liked or disliked about them. Also I have a white boat. Any idea if I can use black covers or might it rub off on the boat? Might just do white to be safe.

I have the white ones. They have been fine for the last 4 years. This is on my aluminum salmon boat that does not get power loaded. I haven’t seen any rub marks on my off white painted hull.
