My conservatory is a fairly dark stained cedar (at least, I'm told it's cedar - probably doesn't matter). Since it needs a bit of a revamp anyway I am planning to brighten it up by painting the inside sides of the wood. The outside will stay as wood, with regular coats of preservative. It does get pretty warm inside and there's some evidence of leakage that I'll need to repair before I start painting.
Does anyone have any hints, tips, warnings etc. about the types of undercoat or paint to use.
