OK, more and more of the paint is getting removed so that the true extent of the work can be determined. This way a thorough and professional job can be carried out with no surprises to catch you out at a later date.
Having a really solid and sorted base makes the final preparation and paintwork easier, plus helps get a much better final result. As with most things in life, preparation is key!

This is why it is great to get the paint all off to discover what potential nasties lie beneath. All issues such as this will get sorted correctly so that it becomes a 100% solid and sorted bus once again!
