I ripped this from http://www.vgautopaints.com.au/
It can go over almost anything as it's also a sealer.
Paint. Metal. Filler and more.
Its a primer/putty that is extremely high building and fast curing. It is also WATERPROOF.
So its fine to be left unpainted for years.
This is perfect for restorations where you want to take your time with the body work or repairs.
You can use any kind of paint on top of it, Acrylic, 2 Pack or even Enamel.
Just a matter of rubbing it when your ready and paint it.
Its available at only the best paint shops so if your planning on doing some repairs, go grab some.
