Only the cladding. Rented a HVLP rig, Lined the garage with plastic sheeting, set up a box fan exhaust. House still stunk (I timed it when wife and kid were out of town).
Also sprayed the primer on my '91 S-Blazer after stripping to bare metal, pretty much same set-up, except used a standard spray gun (not HVLP).
I found a local shop that caters to the biker crowd, the guy is pretty good with a gun and has a decent booth (not downdraft, though). He sprayed the color/clear (including door jambs and underside of hood) for $200. He did a really good job.
With me doing all the prep, primer and buying the paint, total cost was $650.
