Reply to "do you dip to strip or blast it off?"

I had my car media blasted, using the soft plastic pellets. While the final effects of removing paint and old bondo worked it has some serious downsides in a monocoque car like the pantera.

First the media is not abrasive enough to eat away the undercoating tar in the engine bay, this area still required manual scraping and a little light sandbasting to remove. This is a minor issue.

The biggest problem is that the media goes everywhere. I must of removed 10 pounds of media in the rocker panels with a shopvac. In the Pantera, I had media in every channel, seam and lap joint many which are unaccessable. It still falls our from time to time in areas. For this reason alone I would not blast another mono car again.

Sandblasting should be avoided on the body surface. With the thin metal on these cars, the sandblasting develops heat which soon warps the body panels.

While dipping might seem to be the next best approach, I would be concerned about the caustic agent in areas that would be difficult to re-apply any rust proofing material. After dipping, you would want to coat the insides of all channels to prevent future rust. The construction of the Pantera prevents easy access to most structual areas.

This is my experience, others might have more positive results.
