I built a contraption to hold swimming pool "float-ies" out of galvanized pipe. I had no idea it was going to be so hard to paint however. I've sanded it somewhat, used mineral spirits to remove the stickers and gave it a good washdown with TSP. What would you recommend for a primer/paint choice? I was hoping to use a rattle-can to spray it, but I'm not finding anything that I'm confident won't react with the galvanization. Thanks.
