Ok, I don't know what a bootstripe is - this paint is above the waterline. From just above the waterline, which has a black bottom-cote, to deck-level and the outside kickrail.
I haven't tried wiping it down after sanding to see if the green still comes up or if was releasing green pigment because it was freshly sanded.
I'm hoping to get a good guess as as to what it might be so I can get something new to stick to it without having to completely remove it to the glass/gel.
Not really in a position to completely remove the old paint and use something like Brightside or Perfection.
It's been such a long time since I've had to sand old paint that I'm not familiar with how powdery the old coatings come off.
Whoever did the original paint-job used some kind of red/coppery primer under the deck
coat, a very thick layer, and I'm not sure if that's normal for use on fibreglass or not.
The topside of the boat has the primer, but the outside of the hull
above the waterline has this green paint directly on the fibreglass/epoxy
