I've been working on some simple shutters by gluing strips of 1/4" poplar to both sides of 1/4" MDF, creating a raised panel effect. (see photos). Recently the weather in the Northeast US changed from warm and humid to cold and dry, and a few of my assembled-but-not-finished panels have warped. I was hoping to get them painted before this happened but nope.
In designing the project I'd also hoped the MDF core would keep everything straight. No luck there either.
Other than remaking the panels and hoping for a better result, is there anything I can try to straighten them out prior to painting? Thanks!
