Take it's all encompassing,but if so/how 's that work in relation to fitting it back on to stub axle ??. Added thought bearing removal/Powder coating/replacement bearing front wheel.
They won't powder coat the splines unless they are complete idiots Leave the original bearings in while it's being coated, then change them for new when it comes back. Take the valve out the rim as well, use a new one.
They blast them first, then electrically charge them so the powder sticks to the metal then cook them
I always tape over areas not to be coated and or use something like a wood broom handle to keep crap out of splines etc.
