I notice photos on the internet showing people have customized their cars by painting parts of them with Plasti Dip. They seem to get a smooth surface. The last time I tried a product by that name, it was sold as a way of creating tool handles. You were supposed to dip the tool handle, not use a brush. I found it hard to get a smooth surface. Has Plasti Dip become a new product? Or do the car customizers thin it with something?
