Yeah, I see your point...I guess we kind of have a tendency to just "think" of it as another piece of cladding because of the color, like you said. Although mine is definitely a lighter color, not a black, not even a dark charcoal color, so maybe mine was treated/painted/coated with something to make it that lighter color, like I believe my cladding was.
I found the darker charcoal cladding looked fine with the insert as is. I think I'll leave it alone for now. Let the R/R continue to peel off.
I also noticed in the bright sun, (vs the overcast sky when I took the pics) the cladding does have a slight sheen to it, not shiny, but definitely a little satin/sheen. I liked it!
Follow Up observation...I was on several dirt roads today and after I got home, I again noticed the cladding had a little less dust/dirt than before. There's still some there, but it's definitely "less". Why, I don't know....
I bought a little 5 oz glass jar with a rubber seal at the hobby store for my mixture. It has very little air space in the jar and hopefully won't dry up and will be useable for quite some time.
As I was out and about all day today driving around, every time I came walking up the truck, I was so happy with the color. Kinda embarassing how such a stupid little thing can make one so happy...
And you know what they say...."if momma ain't happy, aint nobody happy"!
