I had a few rust freckles under the trunk mat on my new old car. Cleaned it up treated it with The Must For Rust. This stuff is great it chemically changes the FeO2 rust to another compound thereby killing the rust in place.
Anyway I need some ideas or suggestions on how to better match the larger gray splatter than the rattle cans produce. I got the duplicolor and tested it on cardboard and it shoots out black paint with a smattering of tiny gray splatter. I need something closer to OEM look for the floor. I know... nobody will see it under the mat but it will keep me up at night because I KNOW ITS THERE UGH!
