Bottom pain is a common name for various products.
- Primer... well I guess you know what a good primer doe.
- Osmosis protection or Blister protection prevents water from damaging the hull. This is a chemical reaction, water does not penetrate the hull but reacts with water and chemicals inside the hull.
- Antifouling slows down the buil up of growth and prevents it from attaching more permanently.
If your boat stays in the water for a couple of months a year, the best solution is to apply different layers: (Primer, depending on surface) - Osmosis protection (2-3 layers) - Primer - Antifouling (2 layers). This is not cheap, but gives peace of mind.
Coming back to resell value: what depreciates a boat more? Blisters or bottom paint?
Yes, you can argue that there is a good warranty on the hull... But that doesn't prevent you from applying extra protection/insurance.
