I'm finishing an Aeronaut Diva, which has a sheeted over frame hull. The bottom of the hull is normal birch ply, the sides of the hull are mahogany-faced ply.
I used sanding sealer over the whole hull, then several coats of Ronseal Yacht Varnish on the upper hull.
I masked off the mahogany areas, leaving the lower 5mm or so exposed, and sprayed on a couple of thin coats of Halfords white primer. The exposed varnished areas have wrinkled badly, so I'll have to sand back the hull and start again.
This is the first time that I've tried to build a boat with a part natural wood/part painted hull, so I've not tried painting over varnish before.
What paint and varnish would you recommend that I can use together without causing problems? Needs to be something that I can brush or spray from a can, and that I can actually buy during lockdown.
