Mat

You can sometimes fill in and flat off deep cracks with "stopping" which is a type of thick paint you rub in the cracks and sand down with v. fine paper.

I really don't think this will work with yours, as the clearcoat looks to have given up, so will continue to crack, flake and peel.

You could do worse than bring it to a paint shop and ask their opinion. Go to a good one with proper oven bake facilities and so on. If it needs paint, it needs paint.

One last resort you might try. There is a manufacturer of car waxes called Meguiars, their site is www.meguiars.com.
If anyone can give you a short term remedy for your paint, without a respray, these boys can.
