Biohazard

More work on the A/C and heater boxes. Shot this of the heater side before pulling the actuators off so I would have a reference for reassembly.

You can see some light surface rust on the actuator rods which will be steel wooled off. The unpainted actuator looks dull with light oxidation and the steel brackets all have a small amount of rust. I plan to polish the actuator and brush paint the brackets in the interest of preservation.

In the next shot, if you look inside the box behind the open door, you can see a rusty rod upon which a flap door pivots. The door that attaches to it is also rusty as hell.

Here, now, is the flap door and the 2 fasteners that hold it against the pivot rod...

I treated the door with rust converter, rinsed, then sprayed it with Metal Prep, rinsed, dried, then painted it. Ditto the fasteners. The pivot rod just got worked clean with steel wool. Here is the product after painting.

Here is an unpainted actuator after cleaning up. It really only took a light buffing with steel wool to make it look gorgeous.

There is one actuator that must be visible from the cabin and so is painted flat black. Mine had a few scratches so a shot of paint for it was in order. I chose satin black for just a hint of shine.

An actuator returned to its bracket. Note the rust-free linkage rods behind it.

I think I'm going to brush-paint all the rusty brackets at once after the boxes are reassembled. Tomorrow, I will wipe down the flap doors and glue on the open-cell foam panels from the kit. The bare metal parts will get wiped down with oil and the whole hvac assembly should become one, once again.
