Question Airbrush for Small Paint Repairs

I have a number of spots on my paint where I want to sand it down and touch it up. My car is guards red and I have some color mataching PPG Omni MTK Acrylic Urethane. I am thinking that I would get a better appearing application if I use something like an air brush to apply the paint instead of dabing it with a small brush.

I am thinking I will need to add reducer (duh) and hardener to the paint to get it to set appropriately.

Has anyone tried this? Does it work? Are the results ok?

can you use an airbrush ? yes some time ! you first need to be proficient with spray guns of all kinds then with paints and then knowing how to melt in the paint edge . so i would say tuch up with a brush add some hardener to the color let it dry up and shrink in . then color sand and buff it out .

Because your car is Guards red,a single stage solid color a touch -up and color sand and polish is definitely your best bet as 962 stated. You can catalyse it with a little hardener so it wont be gummy to sand on.
I've done many blend ins with airbrushes and professional minijet spray guns,it's not as easy as one might think.

Thanks. I figure there is some art to it but I always like to try new things to increase my bag of tricks.

To my way of thinking a inexpensive Harbor Freight Airbrush may be worth a try to see if it is something I can use.

If you are going to use the air brush, PRACTICE, PRACTICE, PRACTICE on something flat until you THINK you have the hand movement down pat. Better to use thin coats, let dry and hit it again.

Cheers,
Larry
