Michelle Guerrero, or Mr. B baby, as she's known on the street, has gone from unknown artist to one of the most recognizable muralists in San Diego.

Her work centers around a whimsical wolf piñata named Chucho.

And she's kind enough let me help her spray paint this mural.

I'm hoping she doesn't regret it.

I've never been next to someone who's used spray.

So can I see you do a little bit of it?

So basically, this is drive.

This is go up.

You get this lever and just push it towards you.

If you want to go down, you push the opposite.

Can I?

- I want to try?

- Yes.

oh wow!

This is super fun!

How high does this go?

Keep going until it stops.

I think it goes about 20 feet.

And now we're going to go to the next building.

Oh, wow.

What do you need to paint?

Um, I could do some of the fur.

- Right here.

- Here.

- This is the hair of Chucho.

- Yup - I love!

- Do you want to try?

- Yeah.

- Go close.

So it's all about the pressure the fingers.

- Did I mess it up?

- No no, youre good.

So I use three colors.

Like, basically, it's my dark, my medium and my light.

And then I get.

I have, like, some parts where I hit it with an extra layer.

- Ah, to give it the dimension.

- Yeah.

Like that?

Mm hmm.

So this mural took you how many days or will take you how many days?

It's been like two days, cause today...

This has been two days only!

Yeah.

You.

You're kidding me?

No, for real.

I would have thought that this would have taken you like 10 days or something.

Come down.

You're like, No, I want to keep painting.

Im like, but this is much fun.

Im kidding.
