I have been using this product for a while to restore the “black” in the plastic claddings in the various cars. This is the best of such products I have ever tried, it’s a kind of dense and transparent fluid and works very well, a little goes a long way. I’ve used it also in the trailer to restore the look of my batteries cover box, the tongue jack, bottles cover, cladding around the wheels (this is not a Lance).
Last week I found another use that maybe someone already know, but I feel it’s worth mentioning. I was working around the trailer which is five years old and I noticed that the black color on the steel frame is kind of “faded”, with a significant haze on top of the black. You wash it and as long as it’s wet it looks great, but when it dries up it’s old and tired. Mostly noticeable on the tongue, the back bumper and the corner jacks.
Well, I had the Trinova in my hands and I applied it on a small metal part... long story short, it works miracles, it brings back the original deep black, no residual stickiness at all on the surface. It actually seem to leave a film that should be protecting the paint. It really took away several years of age from the appearance of the trailer! I’m going to use it even more extensively from now on...
