I am now finally going to get my interior resprayed and a friend has agreed to do it for me. My interior will be bare and have no carpets. What is the best thing to paint the floor so its fairly hardy and doesn't rub off the first time you get in. I was wondering if I could use a red underseal or something similar that is thick and strong enough to withstand getting in and out of the car. Someone did mention a product called Schutz. Is this suitable?. Obviously spraying the rest of the interior can just be done with conventional car spray. Any help would be appreciated Pete.
