69Charger, Ive been following this thread from the beginning and I was just wondering.If I decide to spray a panel as a test,should I still use mineral spirits and water it down as I would rollering? I,ve scrolled through a bunch of these pages and havent been able to find where anyone has asked about this.I,m going to try rollering a trunk lid in the next week or so but I want to spray one side just to compare the two! Thanks and great thread!
