Default how do I mask off a perfect circle for track car?

I am prepping my track and want to paint some large circles on the doors and on the roof and hood.

Question, how do you tape/mask off a perfect circle. I am thinking some like 16 inches in diameter. Others up to 30 inches.

Is there a bodyshop product that is like tacky paper that can have a perfect circle cut out with a string and knife?

Vinyl...why bother with paint? 30" is easy to accommodate with vinyl.

I want an odd color. That is why I did not want to to vinyl. And I also want it to be matte finish.

One way is vinyl mask. Get a 30" or 16" circle in vinyl

Get vinyl cut out and use acrylic paint on top of it, then you can replace or change if need be. Or you you can buy pre-mask from a sign supply company..that can be trimmed w/ a knife. We use it for spraying custom graphics.

No kidding, I can paint a vinyl cut out and it won't peel or flake off? That would be the easiest.

I'd think you would have to apply the vinyl first, and then mask and paint while it is on the car. It should stick fine, until you decide to peel it off, then the paint would probably flake.

You could just cut the bottom out of a large bucket... hold it up to the car and spray inside the bucket!

I gotta think that with a magnet, some fishing line and a little creativity you could come up with something to strike a perfect arc.

Stupid question... if it's a track car, why does it need to be perfect???

I did mine with masking tape, back when I ran meatballs; drew on a circle, then taped around it.

Good enough for the spray-bomb paint I finished it in...
