G10 fin preparation for primer/paint

[Dave S.]

I was looking for recommendations for preparation of G10 fins for primer and paint.

I’ve seen a number of threads related to the preparation of filament wound fiberglass, but I was wondering about G10.

I would have thought the same prep would do for both. Both are remarkably similar. I personally don't treat them as different.

Thanks. Thats what I expected. Wasn’t sure if there was some sage wisdom on this.

The only difference, IME, is that G10/12 sheets usually have a glossy finish. I use 320 or so to knock that off.
