All of the old self-polishing bottom paint has been removed. We scraped it off with a ProScraper, then sanded it with a 120gr orbital sander to get rid of any residues. The hull has been epoxy treated before and the old barrier coat was still intact in most places. We decided to apply a new barrier coat on top of it anyways, as this is the perfect opportunity and we don't want to redo this job in the near future.
We choose Lefant's Epoxy primer which is a quite thick epoxy barrier coat that can be painted down till +5 celsius degrees and makes a watertight seal after even 4 layers. As we already had a barrier coat we decided to go with 4 layers and iterate between white and black colors to make it easy to get a good coverage. We used 12 liters of primer in total (one 3 liter can was just enough for one layer).
