Around $250 for a set of aluminum covers vs $25 for caliper paint was an easy decision for me.
I started epoxy coating my calipers on my vehicles about 20 years ago, so I'm very familure about how long it last and looks good.
But after you paint them again, then again...it gets old.
Personally I just got tired of the re-painting every few years, but then, I probably keep my truck cleaner than most too.
Mines not a daily driver so it's always spotless.
It was well worth the $250 for me, plus no more brake dust on my clean wheels!
I guess it just comes down to value vs cost, that was a no brainer for me.
