I think my problem was how cold it was. I think the metal is like about 50 degrees or so when it says it likes it to be 65 degrees to 85 degrees. I'll have to try that on the roof as I go across. Everything else we're all the panels that I can take off the hood the fenders the doors and trunk lid are all done. And I did those in the summer out in the yard where I can scrape them and rinse them off with the hose. Now I'm stuck in the garage and it still isn't super warm in there..
