A reader wants to know: “Has anyone found a prep and finishing system that works well on ACM?
“I like the material because it’s light and easy to handle, but I have had problems with paint adhesion on it, especially if it has a glossy finish. If you’re going to finish the whole panel, you could sand it lightly, but if you want to letter right on the prefinished panel, that’s not an option.
“I’ve tried wiping it down with lacquer thinner then hand lettering it, but once it dried you could scrape the lettering enamel off with your fingernail. How do others make sure the paint sticks to it?”
