Hi Leo, hope this helps you out, You'll need to sand the rust off the area, fill the holes with something like Selleys 50g Knead It Multipurpose Epoxy Putty, sand that smooth and then topcoat with paint. If the rust is terrible, you might like to apply some rust convertor to those locations as well
I have a plastic chair mat under my computer desk that the edges are curled and won't lay flat. Have been unable to bend them back as the plastic is hard
Don't know what that is, sorry.
How big are the holes? Size of screws or size of baseball?
Here's a great step-by-step tutorial with a list of materials that you'll need: https://www.thespruce.com/repairing-a-hole-in-a-metal-roof-system-2902102
