Trying to paint aluminum roof of my gazebo interior side . Will this be good choice ? My gazebo roof is black , will it over paint that color ?

Thank you for your question. Yes, you can successfully use this product on aluminum. Allow new galvanized metal to age six months or clean with mild muriatic solution. Metal should be free of oils and other contaminants. Prime with Valspar Galvanized Metal Primer. Some deep or bright colors may require an additional coat to obtain complete hide.
