How should I prep eaves/facia before repainting

Pawl

4 years ago I cleaned,scraped,primered and painted my eaves and facia wood. A retired painter down the street from me suggested I come back every few years and recoat everything so I dont have to scrape again. Unfortunately he has passed away so I cant pick his brain for answers. Is what he said the best way to go?
Do I just clean and paint the existing wood with the same finish color that looks fine after 4 years and clean,scrape and spot primer any other areas that are peeling?
I have also painted my rain gutters with the same finish color. None of my gutters are peeling. Do I just clean and recoat them? I am using Vista Terminator 2 water- based Primer Sealer Stain Killer on the wood. The finish coat is Vista Carefree Acrylic Enamel semi-gloss shell white. I am putting two coats on everything. This is the same paint I used on the wood 4 years ago. Thanks

If the existing finish is in good shape then clean the surface with a TSP solution or Jomax, bleach and water if mildew is a problem. Wait 3 days for the surface to dry and recoat with acrylic paint. ("nothing sticks to old latex better then new latex").

If the surface has problems then I'd sand and prime first.

I like to use a quality long oil primer with a shot of Penetrol if you have areas down to bare wood.
