Rustproofing and chassis repair pt.1 - surface preparation

In this video I give my approach to rustproofing using a Discovery 1 as an example. In the first part I concentrate on the surface preparation which is the most critical and often overlooked part of the job. Subsequent videos will look the application of surface coatings and the treatment of enclosed spaces.
This video shows my approach to rustproofing and isn't intended as advice for viewers.
