Spring prepapration advice

Thanks for your advice.
I will get the laminating resin from ADC and follow all your advice.

It is exactly like that: "the resin is fractured leaving a corner of the
door attached by some glass weave" .

To me that's a two or three stage job for laminating resin plus a few
square inches of good quality glasscloth.

1) Wet out the fracture with the resin (you can thin it with methanol
if you must but be aware that will weaken the bond) and clamp it to
a former to hold it straight while it cures.
Don't forget the release film.

2) Sand off any lumps on the inside of the door and bond on a layer of
close weave cloth using laminating resin. 100 gsm/3 oz/ft cloth
should do the trick.

3) If the corner was just hanging by a thread, carefully sand off the
gelcoat etc on the outer surface and bond on a layer of light fine
weave cloth, 35 gsm/ 1-1.25 oz/ft weight. There is lighter cloth
but the thread count is low. You'll get a better finish with 35gsm
cloth. Then prepare and glasscloth surface and paint the outer
surface of the door.

Then prepare new glasscloth surface. Use fine sandpaper (180-200 grit on
a sanding block) to get a smooth surface on the glasscloth and feather
its edges before painting it.

The nice thing about good quality 35gsm cloth is that the epoxy usually
fills the weave pretty well. This means you don't need to sand it much to
get rid of the fabric effect after the epoxy has cured.
