We inherited a year old, pre hung, fiberglass front door. Installation went fine ('nother story, 'nother time.) However there are a couple hardware holes in the door that need to be patched and an area that needs to be stained.

Two quesitons:

1. Since the door is stained, I'm wondering what will patch the door and hold stain as well. I'm thinking bondo won't do this.

2. We had to flip the door (see above re: long story) there is a area that's about 3"x8" that was left unstained due to hardware. I've read it's not good to sand down stain on fiberglass. Am I okay feathering it a bit to match? Our contractor suggested we sand off the entire stile so we don't have to worry about matching.

Any help would be much appreciated.

Thank you!

 

Picture sure would be nice.
Any form of filler is never going to match once it's stained.
May be better off just painting it to coverall the flaws.

 

Fillers rarely accept stain well, you might try using a colored putty. I've only finished a few fiberglass doors but while stains can sometimes be touched up - it's not an easy task.

Thanks all. Turns out that staining fiberglass is a PIA, but more forgiving than wood. Matching the color worked fine with blending.

Found some fiberglass safe stripper. That made it pretty easy to remove the original stain and feather it into the original color with a green scotch pad. Then filled the hole with a wood putty that was pretty close in color to the stain. Rather than just plugging the whole, I feather that a bit as well. I had to etch in some "wood grain" where the sanding made it smooth, but that worked fine with a putty knife. Then stained away. Took about four coats, but got a match.

I figured I might as well give it a try, since I could always fall back on painting the door.

 

Hey, if you and partner are happy with it, that's all that matters. Good move on putting the wood grain in. I hope it holds up. No slamming the door! lol
