A heater box can be disassembled, cleaned, foams installed and reassembled in an afternoon. I usually sand (or glass bead) blast the metal "doors" and all brackets. Wash the housing in hot soapy water witha scrub brush to clean out 30 years of movie tickets and leaves. Spray all the metal doors and brackets with a "metal look" quality paint (like Rustoleum Titanium). Then apply high temp spray adhesive to both the door and the foam. Wait for the adhesive to "set up" for a couple minutes and then apply the foams to the doors. Assemble in reverse order and install your heater box and save yourself $300+ having it done!
