I have asked three different paint dealers this question and received three different answers – Is it ok to use a solid latex exterior stain over primed wood trim? One dealer said if the wood is factory primed they used the cheapest possible primer and I should re-prime with an oil based primer and then I can use a latex solid stain or paint. As long as I am mining for information- should the glazing putting on preprimed window be primed also before final finish- I would think so. Is oil base exterior paint better than latex? Any helpful opinions would be greatly appreciated.
