    I have a fiberglass entrance door that gets the full morning sun and is peeling of a clear coat, because it looks like it got sunburn and is now peeling! How do I remove the rest of the clear coat and what would be a good product to apply a new clear coat?
    Thank you, Bill

    When painting a fiberglass entry door, I got an area too thick. I rubbed out this area, but now have a spot that is peeled off or blotchy. Can I just sand that area out and repaint?

    We just stained our fiberglass front door with a gel stain. It took almost 72 hours to dry because of low temperature and very high humidity and the cold humid weather is expected to continue. The door never receives direct sunlight and only limited amount of splashing water. Would a topcoat (spar urethane or others) be required? Can we wait a month for better weather to add the top coat? Also is there anything wrong or a huge disadvantage with the spray spar urethane?

    I am painting the front entry door. I want the inside of the door to be the white of the inside trim but the outside to be a color. Where, on the edge of the door, do I make the transition from white to color? Should the color be flush with the front, wrap around the four edges, or something in between?

    Bill, whenever you're painting a door you paint the edge the same color as the room that the door opens in to. In the case of your front door it opens into the room in your house so it should be painted the color of that room. You indicated white. So paint the edges white. However, if there is already a solid coat of paint without chips on the top and bottom of the door don't bother painting those surfaces. They can't be seen anyway. It can cause the door to rub if they get painted too much. You really only need to include the lock and hinge edges.

    We have a fiberglass door that has a door skin. The front of the door is painted a dark blue and the inside view of the door is white. What are our options? We would love a brown or stained look on both sides. Can we replace the door skin? Should we just paint over the blue? or can we sand the blue off and start over? We also get lots of sun and this door get so hot. Any help is appreciated.
