I ordered a 4mm x 8mm grid for my application. A line of defense should be created between the road surface and the Porsche radiators, which should not withstand an impact. The goods arrived rolled, but above all not crumpled. I unwrapped them with a cylinder I had at home. I did this to avoid creases or dents. Once the mesh was flat I started trimming to give it shape. In the end I was able to add mesh grids at a fraction of the cost of the finished kits and at a higher quality than those kits.
