Fix-a-Flat kits work on a very temporary basis. A punctured tire should be replaced.
Buy a tire pluging kit read the instructions and follow them
A tubeless tire is a tire that does not use an inner tube. A couple disadvantages are they are heavier which results in a decrease in mileage and if the tire becomes punctured it is more expensive to fix.
Buy a new tire.
No, rotating the tires will not fix feathering. Tire feathering is an issue that must be fix, other wise you will keep on buy tires every 2 months ( if brand new), if use tire with in a week or so depending on the condition of the use tire. I learned this from personal experience.
it depends how bad the damage is. If the frame is bent out of shape it would be better to buy a new one but if it's a minor problem like brakes not working or punctured tyres and broken wheels you should just try to fix it.
You should buy a new tire and save the fix-a-flat for your bike.
you can not fix something that is very broken, so buy a new one
Buy something else!

That cannot be done. If broken, the tire is useless.
