I would sand until good wood, to see what the door will look like and
how damaged wood affects it wipe on paint thinner liberaly on the
whole door to see your work, often sanding must start with 50g then
80g then 120 and 200. Be sure to use a product specified Marine, boat
shops or Ben Moore, P&L are top products. The quality is in the prep-
sanding.
