I have a convex soffit that is skinned with 1/4" plywood. The surface of the plywood is reasonably smooth but it does need some sort of covering or coating to make a suitable substrate for a paint finish. My original plan was to curve drywall to fit but I am wondering what other options I may not have given due consideration.

I have done a good bit of DIY drywall and am comfortable with mudding, etc. Would it be practical to prime the plywood and put a skim coat of mud over it? Are there any spray-on options that would leave a smooth finish? What do I do about a "corner" bead? I have seen products for curves but it seems they are intended for concave applications, not convex where the bead is curving back in towards itself.

Your suggestions are appreciated.

They usually wet down 1/4" drywall and bend it and do 2 layers.

These guys do flexi trim molding (coves and more) They have a flack backer board, but idk if its tall enough though. Also their website is atrocious - https://www.trimster.com/home

I am still stuck in the golden oak glory days. So I wouldn't hesitate to put in red oak wainscoting, stained golden oak of course.
