Soft scrub is abrasive and can take the gloss off gelcoat, you want black streak off not paint, if coach is blue paint whatever you use has to be safe for painted surfaces.

I would go the cw store route and checkout more black streak removers without abrasives and advertised as safe to use.
I think if you check it out you will find it says non-abrasive. Been using it for years.
