Thinning paint for brush on

I'm painting the grille of my '46 chevy Panel and the word Chevy and some lines are embossed into it and I want to paint them a different color to make them stand out. How do I thin the paint to use it for applying the paint by brush? I'm using single stage urethane paint. I've got the small mixing cups but I think if I thin it like normal it would be to thin.

Thanks folks

In my experience automotive paints are already too thin for brush work. I usually let a little sit out in the air to evaporate and thicken up a little so it will cover better. Try it right out of the can. If it covers, great. Thin very sparingly, a few percent at a time if necessary. Be sure to add a little hardener B4 brushing it.

If you're using a single stage paint that requires a reducer- (paint+hardener+reducer) just skip the reducer. The paint will be a little thicker this way and will harden just fne. Use a brush with very fine bristles. Should work just fine unless it's a coarse metalic. Bob

I agree with the above.
I painted my metal basement windows last year with
acrylic enamel. I added hardener as usual but didn't
use any reducer. I used a brush for oil base paints.
It went on and flowed out unbelievably well, looks like
it was sprayed on. I think it looked better than some cars
I've seen painted. Hmmm, a brush for car painting????
I've done this to other outside metal
stuff before and it's really held up.
I'm gonna do my gutters with it next.
