Review on Easy, Precise, and Reusable: Custom Shop Body 🔧 Filler Spreaders - 4, 5, & 6 Inch Variety Pack by Mike Palma

These are not "normal" spacers. They are thin and very flexible. They are best used to spread putty in curved areas. The closer to the finished product you can apply putty, the less time you will have to spend on sanding. These spreaders allow you to hold them in a curved shape to achieve this. Since they're very thin, don't put them in the rest of the bondo and try to rip it out as it hardens. Wipe them down with solvent before the filling sets and they will last a very long time. I would highly recommend this product to all serious traders. I am a mechanic with over 40 years of experience.
