Fortunately, we don't do salt here.
As for the primer.. Mine's actually paint. I have gloss black paint that I bought a while ago, but it turned rainy like the next day, and hasn't really stopped
You're going to really hate what I'm going to say next
I let Sarah draw on my car with sidewalk chalk.
As soon as it stops raining, I'll paint my car, and you won't believe it's the same car!
