Don't be wasting the OP's time and money. You can't cover up failed clear coat with a can. Everything must be sanded off then repainted. Don't need the body shop either. The goal should be to get something passable, and not perfection.
As someone whose son drives a 33 year old red Italian car, let's just say that "I've got the T-shirt"! You can, with a bit of work, repair lifted lacquer. Not perfectly, not by a long chalk, but it is do-able, and I've done it.
That said, those photos don't show (as far as I can see) much lacquer "peel" - maybe a patch on the back of the offside rear wheelarch - hard to tell from the photo, but most of it just looks like fading. If it were my car, I'd try some Farecla G3 buffing paste first, and then work down to finer stuff. You might end up going through the lacquer, but of that happens, you're not much worse-off anyway.
The alternate strategy for the OP is simply reduce the price. Nearly everything is sellable if the price is low enough. Rather than using this as an opportunity to learn to paint, which is valuable in itself, he could drop the price. Imagine where the OP would be if he gains the skill to paint? He would be buying a bargain like this, and have a perfectly fine car after.
It's not worth trying to paint anything in this weather, unless the OP has a heated garage.
