I stripped three pairs on the Tensor AGTs, which seem to have REALLY thick paint compared to Thunder and Ace.
Take apart trucks, remove pivot cups.
Coat with a stripper, allow the parts to sit overnight.
Gear up with long butyl rubber gloves and goggles, cover all your skin.
Use a bench vice to hold the truck parts.
Put a wire brush in the chuck of your impact wrench, go to town.
Takes ~20 mins total.
