Thanks
@IwantPrado I'll try to keep everyone updated on how the coatings fare in the future.
Did a thing... Apparently the right front caliper was essentially seized this whole time, wore through the pad and caused a slightly noticeable vibration in the steering wheel I chose to ignore for the past 5k miles. Picked up a Powerstop pad/rotor kit from RockAuto, splurged for the "treated/coated" rotor option to avoid more rust in the future, we'll see how it fares. The calipers is where this whole ordeal gets fun. Apparently eBay OEM refurb calipers are VERY hit and miss, the seals blew out when bleeding both calipers! I was furious, especially after spending about 1 hour priming/painting/clearing the calipers. Argh... Buy it nice or buy it twice I suppose, which is what I ended up doing with 2 new calipers from Autozone. No photos of those but the gray powder coating on them is actually quite nice and matches the TRD wheels perfectly. Gotta make lemonade out of lemons. Truck stops wonderfully now, and the rattles from the missing caliper hardware are eradicated, those were really starting to get on my nerves!
Some photos of the paint process and the condition of the old calipers/rotors/pads. They didn't end up making it onto the truck but some eye candy nonetheless...
Primed + painted with silver paint.
Gold metalcast paint before clearing
Note the missing anti rattle hardware on the old rusty caliper. :-/
Looked good, right until the seals blew out during bleeding. Double :-/
And with Autozone calipers after the bleeding fiasco. Still looks good but not as "bling" as the above. Looking at it more and more, I think its better this way.
