I am desperately seeking information regarding Honduran mahogany front doors. Doors are weathered and appear to have a slight mold problem. I have washed the doors with trisodium phosphate. I know they need to have a polyurethane coating. I have run out of arm power to continue (plus, I do not know what I am doing). I have contacted door companies but they all want to sell me a new door. The doors are beautiful but need to be restored. Also, they are rather ornate in design. Any advice on the appropriate people I should contact? Thank you, kindly!!
