I am removing super old paint off the exterior of my 1/2 1950's 1/2 1993 house. Mostly pealing and then chalky primer underneath the older part of the house. I have most of it scraped off, with the wood showing and now I'm thinking of which primer to use. It's a cedar shingle house with white trim and it is the trim/soffit/window/doors that I am working on. I live in San Diego, Ca if that matters and most painters seem to use latex here. Will the wood bleed through and what does that really mean? Whatever I use I want it to last because this isn't really fun.
