Interesting I did not know that
On another note, I think one of biggest problems with sanding the old gelcoat isn't so much doing the flat areas, which won't take long to scuff up with a power sander. The issue is the non-skid. If a "de-glosser" can roughen it up enough to hold paint, then you don't have to sand through the non-skid which would be a huge job, you could just paint over the existing stuff and add some grit to the paint.
