I've build a PK78 from bateau.com 4 years ago. I've painted the inside of the
dinghy with Brightside Polyurethane. No primer is necessary but removal of amine blush as to be done perfectly. I've
varnish the outside hull using an International
varnish directly over the
epoxy again being sure to remove amine blush from the
epoxy. I would always
varnish before painting because I find it easier to wipe
paint of
varnish than the opposite.
