No stupid paint questions go here...

Never painted a car...painted a house once.
Here are a few stupid paint questions that would never be asked seriously:

What makes automobile paint 'auto' grade? At >$200 a gallon?

They have high gloss paints at Home Depot in pints, even metallics... could you paint a car with that paint and then wax if it is a garage stored weekend car?

I've seen cars painted with a roller (as a joke?) And they came out pretty good for a roller, not sure how much color sanding was done but I understand its done in about 10 very dilute coats with a small foam roller.

Could you paint a car with a Wagner (airless) power painter? With what results?

I understand every one of these questions is ludicrous but let's here some softball answers you would tell your 5 year old questionnaire.
