I've made several radiator covers for my house, but I have several more to go. I've been using mostly plywood rather than solid wood because the exposure to heat made me want something dimensionally stable. I've also been attaching a molding around the top to hide the plywood edge, then I paint the whole thing with latex.

Now it occurs to me that I could achieve a nicer look quite simply by using MDF and router a nice contour. That would also save me from cutting miters in the molding, which is always a challenge. Will the MDF withstand the heat? Do I need to do anything special to prime MDF, particularly around the edges?
