Paint is not designed to be a filler. In fact, it's the opposite. We design paints to lay down as thinly as possible. If your damage includes a dent or divot, you need a filler so you'll have an even surface.
The Isopon Scratch and Stone Chip Filler is the ideal solution for 90% of touch up jobs. The product is easy to use and is specifically designed for the small and most common touch up repairs.
If your repair is on the larger scale then you may want to consider something like the ISOPON Multi-Purpose Body Filler.
This product will help with dents, dings, and deep scratches. If you're ordering an aerosol spray kit, then you should be considering this over the small tube above. Of course, there are still more choices available other than this. Check out all of our fillers here.
