Scraping, priming, and painting (exterior).
Did it for years... not doing it any more.
All the wood siding on the many large and small gables... and fascia has been covered with vinyl and aluminum for several years now.
I can't think of anything that I've ever disliked more. Working my way around the house in spare time when the weather permitted... in some places 16+ feet up a ladder, it always seemed like about the time I finished a lap, it was already starting to split and peel again.
A good bit of the wood siding and fascia was made of heart pine on this late '40's house... you put that in the sun and there isn't a paint known to man that will stay on it.
