It probably won't match what he already has on the garage door.

If using Bondo,I'd form some window screening mesh to fit the large
missing
areas to provide reinforcement(or add chopped glass fiber),since Bondo is
only supposed to be used in THIN layers.



I only have a thin layer missing- 1/16 to 1/8 at most. That is what I have
been scratching my head over- how to get such a thin layer of bondo to
stick well to the exposed fibrous substrate. Afraid that with the first
thermal cycling or hard bump, the whole patch would fall off with some
fuzz sticking to the back of it. No room for screen or screwheads. Afraid
staple-gun staples would be instant rust magnets. Maybe some tiny holes
through the masonite, so the bondo keys in like an old plaster job? Sit
there with the cordless drill and a 1/4 bit, and make a matrix of holes
down into the frame and foam layer, englishing the bit to make the holes
bigger on the bottom?

Not worried about it looking perfect- this is a 50 year old house, and 32
year old garage addition. Just want it to not look horrible. Once bondo
hardens, I can scratch it up enough with sur-form and a screwdriver, so it
doesn't stand out so much from the faux woodgrain.

If you start with a clean dry surface I don't think you will have any
problems with the Bondo failing.

I have some well painted exterior repairs that are fast approaching the 10
year mark. Some of those were at little as 1/32" and others were far thicker
than recommended. Most but not all were sealed with the West epoxy system
before the Bondo was applied. It is expensive but much less than a new door
or panel.
