Just to remove any water from the damaged area, don't use M E K I love that for glass but you are working with laminating epoxy , you can also use a hair dryer to warm the area and drive out water, do not use a heat gun as it may damage the area if you get it too hot.
I use A small palm sander with 60 or 80 grit to prep the surface for the repair.
When sanding, first place baby powder on your arms neck and chest area, I also wear a thin nylon jacket to try to keep the stuff from getting on me because after you sand that crap you will itch.
Wear a respirators or at least a dust mask to keep it out of your lungs. Cover your eyes with safety goggles. Wear a good hat or cover your hair with a scarf, old T shirt or something to keep that dust out of your hair.
When you are done sanding, to remove the dust from your skin first take a cold shower to close your pours and use shampoo to soap up with, then using a flat butter knife go over your arms legs etc with the flat edge of the knife in only one direction similar to shaving so that you remove the glass dust and not push it in your pours.
Then take a hot shower to get what you can out of your pours and off your skin, And have fun sleeping. I use sun burn spray for the remaining itch from the glass powder.
DO NOT throw the clothes you used in the laundry or you will probably have to change your name and move to another country. Use clothes that you can throw away after you do this even if you wash them by hand you will never get the dust out completely. haa I am itching just thinking about this!
I have a designated thin nylon jacket that I wear when I sand glass or epoxy, I even tape the cuffs tight on the sleeves because your hands are making all the dust so it goes straight down your sleeves.
honestly If you have insurance you would do better to have the hull fixed by a pro and not do it yourself. I owned a paint, body , auto repair and welding shop many years ago and I hate doing glass work so I know you will not enjoy this and when all is said and done with no experience it will probably end up being an obvious repair especially where yours is damaged , The old saying do it right the first time and move on.
