Real figures from this job.

The problem

Decades of paint, filler and surface rust on every panel, plus the inside of the shell. Sanding would take weeks and still miss the seams.

The setup

A gas pressure washer, the Tank Rig and a canopy for shade. Plastic over the glass and the interior, a tarp under the car to catch the media.

How it ran

  1. Mask the glass, openings and anything you keep
  2. Rockers and lower panels first
  3. Roof and upper panels, top down
  4. Jambs, edges and seams with the ceramic nozzle
  5. Inside surfaces, their own pass
  6. Rinse the whole shell, then treat it

The finish

Inhibitor in the last rinse, AP1 on the bare steel, primed the same day.

What you need

  • Plastic over the glass and the interior
  • A tarp under the car to catch the media
  • Eyes, face and hands covered

Finish, in order

  1. RinseRust inhibitor in the last rinse
  2. DryBlow the water out of every seam
  3. TreatAP1 on the bare steel
  4. PrimeThe same day
Carbide 600 on the shell: red paint down to grey steel.

Questions

Did the panels warp?

No. Warping comes from heat, and water keeps the steel cool while it cuts.

Why 15 bags for one car?

One bag per panel face, and the inside counts again. The media calculator in the blasting guide plans yours.

Could I do it with the Bag Rig?

Yes. The gravity bag does the same work; you stop to swap bags. The tank just keeps you going.
