Powder coating calipers

[Clatter]

Why couldn't the seals/pistons be left in place during powder-coat?

The seals are going to be hi-temp material, as brakes get really hot during heavy use, right?

powder coat ovens are 350F or so? Anybody know?
Do brakes get hotter than that?

So, not to have to spend a sack of money on the rebuilt kits (944T),
why not leave it all together and powder-coat?

If all of the passages were plugged, and the seals never got sandblasted...

Why Not?
