Hi, I'm Steve Smith with Camper Van Freedom. This is my Dura-Gold contoured hand-sanding block kit. I did not use every shape, but the profiles I used did the job well. I liked the sandpaper and considered the kit good value, even though I did not need the entire assortment. The matching product picture shows several curved working profiles and the handle arrangement. The set includes convex and concave shapes. Hook-and-loop surfaces hold the abrasive against the selected profile. The block supplies the supporting shape, while the sandpaper is the replaceable material doing the sanding. My build photographs show the heater-opening area during finishing and after white paint around it. The preparation work included cut edges and corners as well as a surrounding flat area. Those photographs provide the broader finishing context for the sanding supplies in my kit. The workshop footage illustrates general measuring and holding work. Shape and grit are separate choices. A flat face and a curved face support the abrasive differently against the work. The grit describes the abrasive attached to that support. Changing one does not automatically change the other. That is the useful distinction behind a collection of shaped hand blocks. My experience with this kit was good value. I did not need every block in the assortment. The profiles I did use worked well for my purposes, and I liked the sandpaper. Having unused shapes in the case did not change that assessment of the parts I actually used. The cut opening and painted area help explain the stages around the finishing supplies. Cutting came before abrasive preparation and coating. Corners, edges and broad flat faces presented different working shapes. A chosen block supports the abrasive against the area being worked, rather than making every profile do the same job. My page compares two researched alternatives. The three M rubber block has a more uniform rectangular support. The Dura-Block standard block provides a longer rectangular working face and hand grip. Their matching pictures show simpler fixed-shape formats beside the contoured assortment. They are comparison options, rather than the kit I reviewed. Thanks for watching. I'm Steve Smith with Camper Van Freedom. I did not use every Dura-Gold block, but the profiles I used worked well, I liked the sandpaper and the kit was good value for me.
