My 7 year old fiberglass door has light areas that have lost the woodgrained look. I tried to stain the door with a gel stain, but the light areas did not take the stain. What can I do?
Stain does work on fiberglass doors as long as it's the right type of stain. This isn't wood so different procedures are needed. Check out this article for more info; <a href="https://www.house-painting-info.com/staining-a-fiberglass-door.html">Staining a Fiberglass Door</a>
