The drivers side strut tower and inner wheel arch was much the same process as the other side so I won't go through all that again.
One job that I had been putting off for some time was to clean the underside of the years and years of underseal and mess that had gathered there, not a nice job.
The black underseal was scraped off using a heat gun and a wallpaper scraper, best combination I find for that job. Messy and hot, but best.
Once all that was cleaned off then we were down to the factory rubberised stuff that I use a knotted wheel on an angle grinder to take off, this flings it about a bit but cleans it efficiently and also if there are any rust spots under it then it cleans that too, just be careful not to have exposed skin as the little needles off the knotted wheel easily stick in your cheek! A full face mask is a must, not just goggles.
