Yes I used endura primer
Outside only
Mike
Primed inside and out. Living in California as you and I do, you will likely want to visit the coastline. Sprayed the outside and pored it into the inside with tennis balls to hold it in. I mixed up too much primer. One cup of mixed primer will do the job on one spar with plenty of left over. I mixed up about a half of a quart of primer then catalyst and reducer. Makes too much. Wasted plenty.

Primed inside and out with poly fiber white epoxy primer. Rigged an airbrush on the end of a piece of pvc to spray inside spar with a tennis ball on the end.
