i hope you craftsmen out there can answer some crucial questions about my factory primed 1/2 x 7″ clapboard, 5″ exposure. if there is a buttjoint should the edges be primed and then run a small bead of caulk, then push the two pieces together or should i use pl premium or gorilla glue? i think the material is too thin to scarfjoint them. some of the clapboard varies slightly in thickness. so i think using an orbital sander should fix that. how much space where the clapboard meets the cornerboard? for the caulking issue, is dap painterscaulk good enough or dap alex plus much better. any fhb magazines with more info. thanks for all your help past, present and future. i am restoring my 1920 home and i don’t believe in shortcuts. thanks again.
