I actually got into metal casting and blacksmithing because one day I tried using my dad's shop vac to blow air into a fire I'd made in the backyard. The shop vac was about as strong as a leaf blower and was extremely effective.

After that I dug a small pit, trenched a 2" pipe into the bottom of it to act as a tuyere, and then hooked the shop vac hose to the other end of the pipe. That fire got hot enough that some rocks lining the pit glowed white and sand started to clump together. I could toss an 8-10 inch piece of (undried) oak log into the fire and it would completely burn away in under ten minutes. I had used an old log holder from a fireplace made of 3/4" iron bars to allow airflow around the larger logs as the fire was starting. When the fire died down I discovered it had completely buckled and collapsed from the heat.

I went on to learn how to make refractory bricks and distill charcoal. I switched from the shop vac to a computer case fan for my actual forges though, as the shop vac easily blew all the charcoal out of the fire pot and was very loud.

I use it to dry my car which is ceramic coated, one of the best tools I have recently purchased.

why would you dry a car instead of buy one that is water proof

i would be leaf blowing my car every other day with the amount of rain here

I'm sorry, is this is sarcasm?

When you wash the car you want all the water off of it. Water isn't clean.

water spots lol.

I have never dried a car, does a car not dry by itself?

I have never dried my own cars but my dad and grandfather insisted on towel-drying cars to avoid water spots.

Though come to think of it, a leaf blower might not work for that, unless it's actually managing to remove the water mechanically and eliminating evaporation. I recall mechanized car-washes using blow driers so maybe this does, indeed, work.

You're from a great line of dads!

When you wash the car properly, you want to remove the excess water as it's not clean. Most people do this with a microfiber, towel or chamois. These can scratch the surface if not done properly.

A strong blower will remove the water without scratching the surface. It also works in places too small to reach with a towel.

These same dads insisted I clean the wheel covers because my small fingers could get in the details better :-)

They were car guys, my grandfather got best of class iirc at the concourse d'elegance for a 356 in the eighties. Now I own no car (but many bikes!)

There are also something called "water blades" - soft strips of plastic/silicone that can be used to sweep water off car surfaces.

edit: Sorry I meant when I wash the car. For some reason I thought that was obvious.
