How much CFM recommended to blow dry tight spots and possibly the whole car?

I don't have compressed air so I figured I would maybe get a shop vac with a good CFM and that could do the trick for some certain areas to blow dry.

So I was wondering how much CFM should I aim for?

I have a cordless Makita that gets about 90% of water out of tight spots easily. It’s 91 cfm and very lightweight and very small. 1 battery gets me through about 2-3 cars on highest setting. The problem I always encounter is that somedays you can’t always blow air into even the tightest spots. For example I’ll blow dry the water around the mirrors and water +gravity from the weather striping will always work it’s way down and you’ll end up with 1 drip about 5-10 mins later. At that point it’s more about technique rather than cfm. But the little blower is great has a full rubber tip so you won’t scratch the paint as well.

I want a shop vac and I've been wanting to get a leaf blower to dry the car and Ridgid makes a vacuum that they advertise as having a detachable leaf blower too. People say it's not strong enough as a leaf blower but I've been wondering if it's strong enough to dry my car with.

Scott at Dallas Paint Correction loves that Worx unit. It has 600 CFM and it's like $50.

Nice. I got a Milwaukee one but it seems weak and the specs are only 40 CFM. I will probably try to sell it ans get another one.
