I'm in the process of replacing the padded dash with a redyed original off of wreck. The new one is faded but uncracked. However the speaker grill that I replaced just 4 years ago is badly warped it's buckling up where it faces the dash between the screw holes. There's a new one going back on it but Anyone have an idea how to prevent the new one from warping like the previous one. The OEM grill cracked but didn't warp.
