Being the hoarder that I am, I had managed to acquire a couple of spare sets of black cube trims over the years and finally got around to doing something with them. All of the pieces, including the ones installed in the car, had varying degrees of wear and scratches so I've been meaning to do a mini-restoration for a while. Could always just redo it in semi-gloss black but fancied a bit of a colour change and went for a silver tone to sort of emulate the clubsport silver trims. Went to Spraystore, showed them what I was after and instead of custom-mixing something they recommended the off-the-shelf silver wheel paint, which was pretty close to the tone I wanted.
Gave the pieced a light sand with 600/2000 grit, masked off the inner edges on a few pieces, wiped down with alcohol and gave them 3-4 light coats (10 minutes between coats), followed by 2 coats of matte clear for a bit of protection. The coats were light enough to retain the cube texture and not look too dull.
Might have turned out a tad brighter than I would have liked but on the whole I do quite like it. Will see how I feel about it in a few months' time but so far I'm pleased with the outcome.
The wife said she liked it better all black. I guess haters gonna hate.
