I removed the rubber floor mat from my ute and there is surface rust on the floor. It appears that it was painted with a red oxide primer originally. Is this still available or what should I use instead. I am not a panel beaters or painters backside..... so go easy on me? The windscreen was replaced and a round top screen rubber was fitted instead of a square top rubber so it will be coming out again. I didn't notice at the time until my mate from NZ was using the car soon after the screen was replaced and he got soaked when it rained heavily.
Thanks

Red killrust must be close? But you won't see it anyway as HK said.

As I said you can buy a substitute that looks the same but it isn't red lead. I don't know if it is an acrylic anymore either so make sure you don't try to spray acrylic over it.
