Not if you use Danbolin which is designed for the job. I have just repainted my engine bay (while the engine is out). Most of the original Danbolin from 1979 was intactIf you paint your bilges you’re adding a new regular maintenance item to your list every couple of years. Dirty GRP is just dirty, but it will happily stay that way. paint flakes off eventually and becomes a nightmare that will need to be regularly stripped and redone. My old boat was painted and I regularly cursed the previous owner. All you’ll see on here is pictures of lovely new painted surfaces looking nice, never of old dusty flaking ones a few years later. Always consider painting a very very last resort if you want to go boating. If you like working on boats then paint away, it will look nicer for a year, maybe two, and then you get a nice new project.
