Depends on the leaf blower, but the one I put a link for is strong enough that it's super loud. You have to put it up next to your head to blow a roof off so it can get right next to your ears. I just have some old over the ear protection I leave with it and put them on really quick. Also just be sure you don't end up blowing dirt off the ground and up onto the car.

For the quick detailer maybe go with the McKees 37 in this link. I'm a little confused with the CarPro lineup for that part actually after looking into it:

CarPro Reset is their wash soap.

If you look at crspotless.com that's the filters for washing cars. As far as I know it's pretty much the only solution I've ever seen for spotless water, you only use it during the final rinse so you save the filter usage. I have the DI-120, a lot of people get the one that has dual little ones too.
